Tithi-Nirṇaya for Vratas: Ekādaśī Rules, Saṅkrānti Punya-kāla, Eclipse Observances, and Prāyaścitta
पूर्वतो घटिकास्त्रिंशत्पुण्यकालं विदुर्बुधाः । वृषभे वृश्चिके चैव सिंहे कुम्भे तथैव च ॥ २१ ॥
pūrvato ghaṭikāstriṃśatpuṇyakālaṃ vidurbudhāḥ | vṛṣabhe vṛścike caiva siṃhe kumbhe tathaiva ca || 21 ||
Les sages enseignent qu’en commençant à l’avance (du côté de l’Est/au temps préalable), trente ghaṭikās constituent le temps propice. Cette règle vaut lorsque (la position céleste concernée) est en Vṛṣabha (Taureau), Vṛścika (Scorpion), Siṃha (Lion) et de même Kumbha (Verseau).
Narada (teaching in a technical/ritual-astrology context within the Purva Bhaga)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It emphasizes that dharmic acts become especially fruitful when performed within a correctly determined puṇyakāla, showing that sacred timing (Jyotiṣa-based muhūrta) supports the efficacy of ritual merit.
While technical, it supports Bhakti practice by indicating when devotional observances (vrata, pūjā, snāna, dāna) are most auspicious—helping a devotee align worship with dharmic cosmic order.
Vedāṅga Jyotiṣa: the verse teaches a concrete time-measure (thirty ghaṭikās) for defining an auspicious window connected with specific rāśis (Taurus, Scorpio, Leo, Aquarius), useful for muhūrta and ritual scheduling.
