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 ||
Quando a Lua e o Sol se movem em ayanas opostos, com suas longitudes (krānti) registradas até os minutos, e se alinham com exatidão, então ocorre o yoga chamado Vyatīpāta—na meia‑volta do ciclo da revolução (bhagaṇa)—dotado do poder do tapas (austeridade).
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.
