उदीच्यवृत्तिरसमे प्राच्यवृत्तिस्तु युग्मके / सपञ्चमश्चतुर्थांशे युगपत्तौ प्रवृत्तकम्
udīcyavṛttirasame prācyavṛttistu yugmake / sapañcamaścaturthāṃśe yugapattau pravṛttakam
Lorsque le compte est impair, on accomplit la règle selon le mode du Nord (udīcya) ; mais lorsqu’il est pair, on l’accomplit selon le mode de l’Orient (prācya). Dans le quart de portion qui comprend le cinquième pas, il faut agir simultanément, selon l’ordonnance.
Lord Vishnu (speaking to Garuda)
Concept: Correct procedure depends on parity (odd/even) and prescribed sequencing; simultaneous execution is mandated in a defined segment.
Vedantic Theme: niyama (discipline) and śāstra-prāmāṇya (authority of rule) as supports for right action.
Application: When applying a counted procedure (metrical/ritual/recitational), switch mode by odd/even count; execute the specified portion simultaneously where instructed.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.208.9; Garuda Purana 1.208.10; Garuda Purana 1.208.12
This verse gives a rule-based distinction of ritual orientation/mode: odd counts follow the northern mode (udīcya), while even counts follow the eastern mode (prācyā), preserving correctness in prescribed rites.
It functions as a technical instruction within ritual chapters: correct sequencing, orientation, and whether actions are done separately or simultaneously are treated as dharma-critical details in śrāddha/piṇḍa-related observances.
When performing tradition-based rites, follow a consistent, text-grounded procedure (including count-based rules and timing). If unsure, consult a competent priest/scholar to maintain ritual accuracy and intention.
