Narada (teaching within the Uttara-Bhaga context of ritual timing and observance)
Vrata: tithi-vrata (general; not a named vrata)
Primary Rasa: shanta
Secondary Rasa: none
It teaches that a tithi-observance becomes spiritually effective when it aligns with sacred timing and pleases the Pitṛs; completing the fast through the tithi’s end is presented as the essential discipline that yields amplified merit.
It frames devotion as disciplined observance: honoring divine order through correct timing (kāla-jñāna) and reverence for ancestors, thereby cultivating steadiness and sincerity—qualities that support bhakti-based life practices.
It highlights kāla-nirṇaya (time-determination) connected to Jyotiṣa Vedāṅga—specifically, observing a vrata according to the tithi’s boundaries and completing the fast up to the tithi’s prānta (end portion) for full result.
