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 ||
Kapag ang Buwan at ang Araw ay gumagalaw sa magkasalungat na ayana, at ang kanilang krānti ay naitala hanggang sa minuto at naging ganap na magkatapat, sumasapit ang yoga na tinatawag na Vyatīpāta—sa kalahating ikot ng pag-inog (bhagaṇa)—na may lakas ng tapas (pagpapakasakit/ascetismo).

Vrata: none

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.
