Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
विपटीतायनगतौ चंद्रार्कौ क्रांतिलिप्तिकाः । समास्तदा व्यतीपातो भगणार्द्धे तपोयुतौ ॥ १७५ ॥
vipaṭītāyanagatau caṃdrārkau krāṃtiliptikāḥ | samāstadā vyatīpāto bhagaṇārddhe tapoyutau || 175 ||
Lorsque la Lune et le Soleil cheminent en ayana opposés, leurs longitudes (krānti) relevées jusqu’aux minutes, et qu’ils s’alignent exactement ainsi, survient le yoga nommé Vyatīpāta—à la demi‑révolution du cycle planétaire—porteur de la force du tapas (austérité).
Sanatkumara (in dialogue with Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames Vyatīpāta as a time-condition carrying strong tapas-like intensity, implying that actions performed then can become spiritually weighty and therefore require discernment and purity.
While technical, it supports bhakti-practice by emphasizing right kala (sacred timing): a devotee aligns worship and vows with dharmic time-knowledge so that devotion is performed with greater steadiness and fewer obstacles.
Vedāṅga Jyotiṣa: it defines Vyatīpāta yoga through Sun–Moon positional relations and precision units (liptā/minutes), showing how calendrical astronomy informs ritual timing.
