Authentic Classical RuleScriptural Injunction:
“Observed on Ashadha Purnima remaining for at least 3 muhurtas (6 ghatis) after sunrise. Sannyasis commence their Chaturmasya Vrata on this auspicious day.”
No classical authority is recorded for this determination in our catalogue.
Kāla Vyāpti Principle: Vedic festivals are not determined solely by Gregorian dates or standard civil calendar days — the tithi or nakshatra must prevail during its designated Kāla (time portion of the solar day).
For Guru Purnima (Vyasa Puja), worship and vrata rituals are specifically anchored to the Pratah window.
Vrata Discipline & Fasting Injunctions (Niyama)
Consumption restricted to fruits, milk, nuts, and sacred vrat roots.
