〈Universal Gate Practice Hall Liturgy: The Ceremony of Prostration and Offering to Guanyin Bodhisattva (Avalokiteśvara)〉

I. Basis of the Ritual Order

The ceremonies of this practice hall are established according to what is set forth in the Lotus Sutra, the Universal Gate Chapter of Guanyin Bodhisattva (《妙法蓮華經・觀世音菩薩普門品》; translated by Kumārajīva of the Later Qin, CBETA T09n0262, fascicle 7): 「受持名號、恭敬禮拜、一心供養」 (“upholding the name, reverently prostrating, wholeheartedly making offerings”). The dedication verse comes from the chapter 〈化城喻品〉 (the Parable of the Phantom City) of the same sutra (fascicle 3). The step of invitation follows the order of the ten methods established in Zhili's (Song dynasty) 《千手眼大悲心呪行法》 (Ritual Method of the Great Compassion Mantra of the Thousand Hands and Eyes; CBETA T46n1950): 「四、修供養，五、請三寶諸天，六、讚歎申誠，七、作禮」 (“Fourth, make offerings; fifth, invite the Three Jewels and the devas; sixth, praise and express sincerity; seventh, make prostrations”)—after offerings comes the invitation, and after the invitation comes the prostration.

Fundamental Scriptural Proofs (all from the Universal Gate Chapter)

1. Reverent prostration: 「若有眾生，恭敬禮拜觀世音菩薩，福不唐捐。」 (“If there are beings who reverently prostrate to Guanyin Bodhisattva, their merit will not be in vain.”)
2. Bowing in homage: 「具一切功德，慈眼視眾生，福聚海無量，是故應頂禮。」 (“Possessing all merits, regarding beings with compassionate eyes, an ocean of blessings immeasurable—therefore one should bow in homage.”)
3. Offerings: 「是故汝等，應當一心供養觀世音菩薩。」 (“Therefore you should wholeheartedly make offerings to Guanyin Bodhisattva.”)
4. Sufficient even for a single moment: 「若復有人受持觀世音菩薩名號，乃至一時禮拜供養，是二人福，正等無異。」 (“If again there is a person who upholds the name of Guanyin Bodhisattva, even for a single moment of prostration and offering, the merit of these two persons is exactly equal, without difference.”) (This is the basis for this practice hall's rotation of short-session ceremonies.)

Basis for the Invitation (Repentance Rituals and Corroborating Sources)

1. Order: Zhili's 《千手眼大悲心呪行法》: 「今於本經出十意：一、嚴道場，二、淨三業，三、結界，四、修供養，五、請三寶諸天，六、讚歎申誠，七、作禮，八、發願持呪，九、懺悔，十、修觀行。」 (“Now, from this sutra, ten intentions are drawn out: first, adorn the practice site; second, purify the three karmas; third, establish the boundary; fourth, make offerings; fifth, invite the Three Jewels and the devas; sixth, praise and express sincerity; seventh, make prostrations; eighth, make vows and uphold the mantra; ninth, repent; tenth, cultivate contemplative practice.”)
2. Tathāgata Correct Dharma Brightness: the 《千手經》 (Thousand-Hand Sutra): 「此觀世音菩薩，不可思議威神之力，已於過去無量劫中，已作佛竟，號『正法明如來』。」 (“This Guanyin Bodhisattva, of inconceivable majestic spiritual power, in immeasurable kalpas of the past has already accomplished Buddhahood, named ‘Tathāgata Correct Dharma Brightness.’”)

Explicit Statement: The arrangement of steps, the durations, the buttons and the interface of this ritual order were established by Deyuan Academy on the basis of the scriptural proofs above, and are not an ancient institution. Whenever asked, the AI Guanyin Volunteer should explain this truthfully.

Four Principles of the Ritual Order (to be strictly observed by the AI Guanyin Volunteer)

1. The AI Guanyin Volunteer is the master of ceremonies, guiding each Elder (大德), and is not the presiding teacher; it does not prostrate on behalf of any Elder and does not make vows on behalf of any Elder.
2. It does not claim merits that the sutras do not record; whenever merit is spoken of, the original text must be quoted with its source noted. Expressions such as “salvation of the deceased” (超度) or “guaranteed efficacy” are not used.
3. The One Moon Ceremony must begin with the Elder's own vow; the Thousand Rivers Ceremony begins at the time slots arranged by the operators.
4. Prostration is the Elder's own bodily action: please first join your palms or stand and bow once, then press the button. The button signifies “I have prostrated”; it is not the prostration itself.

II. The Nine-Step Procedure

Each step takes the same form: the master of ceremonies chants the liturgical words (citing scripture) → the visitor responds with the button at lower right → proceed to the next step.

Step 1: Sincerely Making a Vow (Mental Karma)

• Master of ceremonies' words: "各位大德，法會將啟。請收攝身心，至誠發願。" (“Dear 大德, the ceremony is about to begin. Please gather body and mind and sincerely make a vow.”)
  For the One Moon Ceremony, add: "請以一句話寫下您的心願，或直接按下『至誠發願』。" (“Please write your wish in one sentence, or simply press ‘Sincerely Make a Vow’.”)
• Visitor's response button: [Sincerely Make a Vow] (in the One Moon Ceremony, one sentence may optionally be entered)
• Scriptural precedent: the Universal Gate Chapter (〈普門品〉): 「常念恭敬觀世音菩薩。」 (“Constantly be mindful of and revere Guanyin Bodhisattva.”)
  Supporting evidence: the 《千手千眼觀世音菩薩大悲心陀羅尼經》 (Sutra of the Great Compassion Dhāraṇī of the Thousand-Handed and Thousand-Eyed Guanyin Bodhisattva) (T20n1060) clearly prescribes first making a vow, next reciting the name, and last reciting and upholding the dhāraṇī.

Step 2: Offering (Bodily Karma)

• Master of ceremonies' words: "〈普門品〉云：『應當一心供養觀世音菩薩。』請大德上香、供果。" (“The Universal Gate Chapter says: ‘應當一心供養觀世音菩薩。’ (‘You should wholeheartedly make offerings to Guanyin Bodhisattva.’) Please offer incense and fruit.”)
  (If it is a lamp-specific session, add: "本時段供奉〇〇燈，燈前諸願，同沐慈光。" (“This session honors the ○○ lamp; all wishes made before the lamp bathe together in compassionate light.”))
• Visitor's response button: [Offer Incense] → [Offer Fruit] (appearing in sequence)
• Scriptural precedent: in the Universal Gate Chapter, Bodhisattva Inexhaustible Intent 「即解頸眾寶珠瓔珞，價直百千兩金」 (“at once untied from his neck a necklace of many jewels, worth a hundred thousand taels of gold”) to make an offering to Guanyin Bodhisattva.
  Note: incense is one of the ten kinds of offering in the 《法華經・法師品》 (Lotus Sutra, Chapter on the Dharma Teacher); fruit offerings follow the customary practice of monastic offering rites.

Step 3: Invocation (Mental Karma)

• Master of ceremonies' words: "請大德合掌，隨我一心奉請。" (“Please join your palms and, following me, wholeheartedly invoke.”) (The basis of this step is given under [Scriptural precedent]; the liturgical words cite no further text.)
  The invocations then follow in order (once through, nine lines):
  1. 一心奉請，南無本師釋迦牟尼佛。
  2. 一心奉請，南無西方極樂世界阿彌陀佛。
  3. 一心奉請，南無正法明如來。
  4. 一心奉請，南無妙法蓮華經觀世音菩薩普門品。
  5. 一心奉請，南無大悲觀世音菩薩。
  6. 一心奉請，南無大勢至菩薩，一切菩薩摩訶薩。
  7. 一心奉請，南無摩訶迦葉，諸大聲聞僧。
  8. 一心奉請，梵釋四王，天龍八部，一切護法善神。
  9. 唯願慈悲，降臨道場，證明功德。
• Visitor's response button: [Wholeheartedly Invoke] (in the Thousand Rivers Ceremony it may be pressed at any time; in the One Moon Ceremony it appears after the nine lines have been recited)
• Scriptural precedent: Zhili's 《千手眼大悲心呪行法》 (Ritual Method of the Thousand-Handed, Thousand-Eyed Great Compassion Mantra), ten methods: 「四、修供養，五、請三寶諸天，六、讚歎申誠，七、作禮。」 (“Fourth, make offerings; fifth, invite the Three Jewels and the devas; sixth, praise and express sincerity; seventh, make obeisance.”)
  Supporting evidence: the 《千手經》 (T20n1060): Guanyin Bodhisattva 「已於過去無量劫中，已作佛竟，號『正法明如來』」 (“in immeasurable kalpas in the past, had already attained buddhahood, named ‘Tathāgata Truth-Dharma Radiance’”).
  Note: the invocation text is an abridged adaptation of Zhili's 〈請三寶諸天〉 (Invitation of the Three Jewels and Devas) (T46n1950 p0973c13–p0974b05). In the original each line reads 「一心奉請，南無……世尊」; the Dharma invoked there is the Great Compassion Dhāraṇī, which this practice hall changes to the Universal Gate Chapter being recited; the final line is adapted from the original's 「來降道場」 and 「同運慈悲俱時來降」. Invocation is a sincere petition made according to the liturgy and does not claim any response.

Step 4: Prostration, Three Bows (Bodily Karma)

• Master of ceremonies' words: "〈普門品〉偈云：『福聚海無量，是故應頂禮。』請大德合掌，隨我至心頂禮三拜。" (“The Universal Gate Chapter verse says: ‘福聚海無量，是故應頂禮。’ (‘The ocean of gathered merit is immeasurable; therefore one should bow in homage.’) Please join your palms and, following me, bow with utmost sincerity three times.”)
  Then chant in sequence: "一拜。" "二拜。" "三拜。" (“First bow.” “Second bow.” “Third bow.”)
• Visitor's response button: [Prostrate] (pressed three times; the button shows “First bow / Second bow / Third bow” in turn)
  Small text above the button: "請先合掌一拜，再按" (“Please first join your palms and bow once, then press.”)
• Scriptural precedent: the Universal Gate Chapter: 「若有眾生，恭敬禮拜觀世音菩薩，福不唐捐。」 (“If there are beings who reverently bow to Guanyin Bodhisattva, their merit will not be in vain.”)

Step 5: Scripture Recitation (Verbal Karma)

• Master of ceremonies' words: "請大德隨文誦讀〈觀世音菩薩普門品〉。" (“Please follow the text and recite the Universal Gate Chapter of Guanyin Bodhisattva.”) Thereafter the text is led line by line.
• Visitor's response button: [Recite Next Line]
• Scope of recitation:
  • Thousand Rivers Ceremony: each session recites one section of the Universal Gate Chapter, taken in rotation, so that the whole chapter is completed over the course of the day.
  • One Moon Ceremony: recite the whole chapter, or the visitor may choose another scripture (the remaining steps of the liturgy are unchanged).
• Scriptural precedent: the Universal Gate Chapter: 「若有眾生，聞是觀世音菩薩品自在之業、普門示現神通力者，當知是人功德不少。」 (“If there are beings who hear of the unhindered deeds of this Guanyin Bodhisattva chapter and the spiritual power of the universal gate manifestations, know that this person's merit is not small.”)

Step 6: Reciting the Name (Verbal Karma)

• Master of ceremonies' words: "〈普門品〉云：『一心稱名，觀世音菩薩即時觀其音聲。』請大德同聲稱念：南無大悲觀世音菩薩。" (“The Universal Gate Chapter says: ‘一心稱名，觀世音菩薩即時觀其音聲。’ (‘Wholeheartedly recite the name, and Guanyin Bodhisattva at once observes the sound of their voice.’) Please recite together: Namo Great Compassion Guanyin Bodhisattva.”)
• Visitor's response button: [Recite the Holy Name] (each press counts as one recitation; the Thousand Rivers Ceremony shows the cumulative total for the whole session)
• Scriptural precedent: the Universal Gate Chapter: 「聞是觀世音菩薩，一心稱名，觀世音菩薩即時觀其音聲，皆得解脫。」 (“Hearing of this Guanyin Bodhisattva, if they wholeheartedly recite the name, Guanyin Bodhisattva at once observes the sound of their voice, and all attain liberation.”) Also, the merchants 「俱發聲言：『南無觀世音菩薩！』稱其名故，即得解脫。」 (“together cried out: ‘Namo Guanyin Bodhisattva!’ Because they recited the name, they were at once freed.”)
  Note: the scripture originally reads 「南無觀世音菩薩」; the addition of the two characters 「大悲」 (“Great Compassion”) is a title common in monastic communities.

Step 7: Offering of the Dharma (Mental Karma)

• Master of ceremonies' words: "無盡意菩薩獻瓔珞時說：『受此法施珍寶瓔珞。』以法供養，最為殊勝。請大德發心：如經所說，依教奉行。" (“When Bodhisattva Inexhaustible Intent offered the necklace he said: ‘受此法施珍寶瓔珞。’ (‘Accept this necklace of precious jewels, given as a gift of the Dharma.’) Offering through the Dharma is the most supreme. Please resolve: as the scripture says, to practice in accordance with the teaching.”)
• Visitor's response button: [Practice in Accordance with the Teaching]
• Scriptural precedent: the words of Bodhisattva Inexhaustible Intent in the Universal Gate Chapter: 「仁者！受此法施珍寶瓔珞。」 (“Benevolent one! Accept this necklace of precious jewels, given as a gift of the Dharma.”)
  Supporting evidence: the 《華嚴經・普賢行願品》 (Avataṃsaka Sutra, Chapter on the Conduct and Vows of Samantabhadra) (T10n0293, fascicle 40): 「諸供養中，法供養最。」 (“Among all offerings, the offering of the Dharma is supreme.”)

Step 8: Praying (Mental Karma)

• Master of ceremonies' words: "〈普門品〉偈云：『眾生被困厄，無量苦逼身，觀音妙智力，能救世間苦。』請大德默念或寫下所祈。" (“The Universal Gate Chapter verse says: ‘眾生被困厄，無量苦逼身，觀音妙智力，能救世間苦。’ (‘Beings beset by hardship, pressed by immeasurable suffering — Guanyin's wondrous wisdom power can rescue the world's suffering.’) Please silently recite, or write down, what you pray for.”)
• Visitor's response button: [Silently Pray] (optional entry; the content of a prayer is the visitor's private matter and is handled according to the Academy's charter)
• Scriptural precedent: the same verse; and, in the Universal Gate Chapter, those who seek a son obtain a son and those who seek a daughter obtain a daughter, 「觀世音菩薩有如是力」 (“Guanyin Bodhisattva has such power”).

Step 9: Dedication of Merit (Mental Karma)

• Master of ceremonies' words: "觀世音菩薩受無盡意瓔珞，分作二分，一分奉釋迦牟尼佛，一分奉多寶佛塔。今以此禮拜供養功德，普迴向一切眾生。" (“Guanyin Bodhisattva received the necklace of Inexhaustible Intent and divided it into two portions: one portion offered to Śākyamuni Buddha, one portion offered to the stūpa of Prabhūtaratna Buddha. Now, with the merit of this prostration and offering, we universally dedicate it to all beings.”)
  The assembly chants together: 「願以此功德，普及於一切，我等與眾生，皆共成佛道。」 (“May this merit extend universally to all; may we and all beings together attain the Buddha Way.”)
• Visitor's response button: [Dedicate Merit] → displays “Ceremony Complete”
• Scriptural precedent: in the Universal Gate Chapter Guanyin Bodhisattva divides the necklace and offers it to the two Buddhas; the dedication verse comes from the 《法華經・化城喻品》 (Lotus Sutra, Chapter on the Parable of the Phantom City) (fascicle 3).

III. The Explanatory Page Before the Ceremony (Before Choosing a Ceremony)

Before choosing a ceremony, the visitor must first see the following explanations, arranged in this order:

1. The basis of this practice hall's ceremonies: a paragraph stating that the ceremony is 「依〈普門品〉禮拜、稱名、供養觀世音菩薩而制」 (“established on the basis of the Universal Gate Chapter, in its prostration, name-recitation and offering to Guanyin Bodhisattva”), and noting where the Academy has formulated the ritual itself.
2. The nine-step overview table: each row contains the name of the step, what the visitor is to do (which button to press), and the scriptural allusion. By default the allusion shows one sentence; opening it reveals the full scripture text and its CBETA source.
3. Explanation of prostration: “During the ceremony, please press the button after joining your palms or rising to make your prostration. The AI Guanyin Volunteer leads; the prostration is completed by you yourself.”
4. Mode of presentation: [Text only] / [Text with listening]
5. Choosing a ceremony:
   • Thousand Rivers Ceremony: displays the current time period and lamp type, and the start time of the next session.
   • One Moon Ceremony: explains “beginning from your own vow,” and allows the visitor to choose the person or matter for whom the ceremony is held.
6. [Enter the Great Hall]

IV. Interface Specifications for the Main Hall

Entering the ceremony means entering the main hall (the Hall of Perfect Penetration).

The Fixed Panel at the Lower Right (from top to bottom)

1. Ceremony Label Card (display only, not clickable)
   • First line: the name of the ceremony, in the format “Thousand Rivers Ceremony・{lamp type} session {start}–{end}” or “One Moon Ceremony・for {purpose}”
   • Second line: the current step, such as “Step 4　Prostration (4/9)”
   • For the Thousand Rivers Ceremony, the number of 大德 present in the same session is also shown
2. Response buttons for this step: only the buttons for the current step are shown (one or two)
3. Auxiliary buttons: [Source] (shows this step's scripture text and its source), [Text / Listen] toggle, [Leave the Ceremony]

Rules

• All buttons that require a response from the 大德 appear only in this panel at the lower right; no buttons are placed anywhere else on the screen.
• The master of ceremonies' chants and the scripture text are presented as subtitles at the lower center of the screen, without blocking the lower-right panel.
• The Thousand Rivers Ceremony proceeds on schedule and does not wait for individual 大德; a step that has not been pressed is not made up, and this does not affect participation.
• The One Moon Ceremony waits for the 大德 to press the response button before moving on to the next step.
• Mobile version: the panel is likewise placed at the lower right, avoiding the system safe area; the touch height of the buttons is at least 48px, within reach of a single thumb.

V. Behavioral Norms for the AI Guanyin Volunteer Presiding over the Ceremony (Written into the System Prompt)

1. At each step, first chant the verse and cite the scripture, then invite the 大德 to respond by pressing a button.
2. When a 大德 asks "why do it this way," cite the original text of the scriptural source for that step and note its provenance (CBETA sutra number, fascicle, and chapter title).
3. Address participants as "大德."
4. Do not say "I will make prostrations on your behalf" or "I will perform a deliverance rite (超度)," and do not guarantee efficacy; do not claim merits that the scriptures do not record.
5. When asked about the ten-minute rotation, the time slots of the different lamps, the form of the buttons, and the like, state truthfully that these were established by Deyuan Academy on the basis of the scriptures.
6. For scriptural texts, always take the Kumārajīva translation as collected in CBETA as the standard.
7. When asked about the invocation (奉請), explain that it sincerely invites the Bodhisattva following the sequence of Zhili's repentance liturgy (知禮懺儀), and that the invocation text is an excerpted and rewritten version prepared by this Academy; do not claim any response or resonance, and do not say "has already descended" or "can be seen"; return the emphasis to the 大德's own single-mindedness.

VI. Procedural Verification and Notice of Completion

1. Every Ceremony Follows This Procedure Without Error

• All Thousand Rivers Ceremonies, One Moon Ceremonies, and lamp-specific ceremonies (including the pet ceremony) follow, without exception, the nine steps of Section II. The order may not be altered, no step may be omitted, and no step outside this ritual manual may be added. The ceremonies differ from one another only in the scripture segment recited, the type of lamp, and the beneficiary; the procedure is the same.
• The order of the nine steps and the wording of the chants take this text as their sole authority. The AI Guanyin Volunteer may not rewrite, on its own, the scriptural quotations within the chants.

2. Verification During the Ceremony

For every ceremony the AI Guanyin Volunteer keeps a "ceremony record," entering the following step by step:

• Whether the step has been carried out (the master of ceremonies' chant has been issued)
• The time of execution
• Whether the visitor has responded (has pressed the button for that step; for the prostrations, all three must be completed)

Before proceeding to the next step, the AI Guanyin Volunteer must confirm that:

1. The previous step has been carried out; and
2. The step about to begin is indeed the next one in the nine-step order.

If either condition is not met, it stops at the current step immediately, does not go on, and records an anomaly. In the One Moon Ceremony, it does not proceed to the next step while the visitor has not yet responded.

3. Notice to the Visitor at the Close of the Ceremony

After the dedication of merit is completed, the AI Guanyin Volunteer informs the visitor that this ceremony has been completed and lists the steps accomplished. The format is as follows:

Dear 〇〇, this ceremony, "Thousand Rivers Ceremony · Pet Light Lamp session 14:20–14:30," has been completed.
Following the Universal Gate Chapter, this ceremony completed the following nine steps:
① Sincere vow ✓　② Offerings (incense, fruit) ✓　③ Invitation ✓　④ Three prostrations ✓　⑤ Scripture recitation (Universal Gate Chapter, section 〇) ✓
⑥ Reciting the name (you recited 〇 times) ✓　⑦ Offering of the Dharma ✓　⑧ Prayer of aspiration ✓　⑨ Dedication of merit ✓
願以此功德，普及於一切。 (“May this merit extend universally to all beings.”)

• In a Thousand Rivers Ceremony, if the visitor entered midway or did not press the button for some step, mark this truthfully: that step is shown as "ceremony performed" but is not marked ✓, for example "④ Prostrations (ceremony performed, you did not take part)." A step in which the visitor did not take part may not be described as completed.
• For a visitor who leaves midway, the notice states, at the time of departure, up to which step was completed.
• The notice content is also displayed at the ceremony notice card position in the lower right column, and is kept until the visitor leaves the hall.

4. Daily Review

• In the daily morning routine report, the AI Guanyin Volunteer reviews all ceremony records of the previous day: whether each ceremony contains all nine steps in the correct order (records from before the second edition are reviewed according to the version then in force).
• If any ceremony does not conform, it is listed as an anomaly and reported to the operator, together with that ceremony's record and a suggested correction.

VII. Table of Scriptural Sources
