उदीच्यवृत्तिरसमे प्राच्यवृत्तिस्तु युग्मके / सपञ्चमश्चतुर्थांशे युगपत्तौ प्रवृत्तकम्
udīcyavṛttirasame prācyavṛttistu yugmake / sapañcamaścaturthāṃśe yugapattau pravṛttakam
Cuando el cómputo es impar, el procedimiento se realiza según el modo del Norte (udīcya); pero cuando es par, se realiza según el modo del Oriente (prācya). En el cuarto de porción que incluye el quinto paso, ha de ejecutarse simultáneamente, conforme a la prescripción.
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.
