Prajāpati-vaṃśānukīrtana — Genealogical Enumeration of Progenitors
Dharma’s Line and the Sādhyas
ततो वेदविदश्चैतां गतिमिच्छन्ति पर्वसु / अविशेषेषु कालेषु ज्ञेयः सवितृमानतः
tato vedavidaścaitāṃ gatimicchanti parvasu / aviśeṣeṣu kāleṣu jñeyaḥ savitṛmānataḥ
Therefore the knowers of the Vedas seek this course on the sacred parva days; in times without special marks, it is to be known by the measure of Savitṛ, the Sun.
