Sanatkumara (teaching Narada in a Moksha-Dharma context with technical time-reckoning)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It grounds dharma and moksha practice in correct kāla (time): vows, worship, and scriptural duties rely on precise day-and-tithi reckoning, so the Purana defines the day by the Sun’s sunrise-to-sunrise cycle.
Bhakti practices (vratas, fasts, pūjā timings) are performed according to tithi and vāsara; by clarifying how time is measured, the text supports disciplined, accurate devotional observance.
Jyotiṣa Vedāṅga: the definition of vāsara (solar day) and the use of bhūta-saṅkhyā (word-numerals like vasu=8, adri=7) to encode large calendrical counts such as yuga tithis.
