FAQs
It teaches that dharmic actions must be aligned with sacred time (kāla); without correct tithi-nirṇaya, even sincerely performed Vedic rites fail to produce their intended spiritual merit (phala).
By stressing disciplined observance—vratas, dāna, and worship done at the proper tithi—this verse supports bhakti as a regulated practice (niyama) where devotion is strengthened through correct, scripture-aligned timing.
Jyotiṣa Vedāṅga (Vedic astronomy/astrology) is central: determining the correct tithi is presented as essential for the validity and fruit of śrauta, smārta, vrata, and dāna practices.
