ក្នុងលោកទាំងឡាយ មិនមានអ្វីផ្សេងទៀតដែលថេរអស់កល្បជានិច្ចទេ; ដូច្នេះ គួរតាំងចិត្តនៅលើអ្វីដែលអមតៈ។ ហេតុនេះហើយ វ្រតដែលហៅថា «នាគវ្រត» ត្រូវបានប្រកាសឲ្យអនុវត្តនៅថ្ងៃចតុរថី នៃខែកើត ក្នុងខែឧរជ (Ūrja)។
Narada (teaching within a vrata/observance context; framed in the Narada–Sanatkumara dialogue tradition)
Vrata: Nāga-vrata
Primary Rasa: shanta
Secondary Rasa: bhakti
It contrasts the impermanence of worldly existence with the need to be established in the eternal (nitya), then links that orientation to a concrete discipline: observing Nāga-vrata on an auspicious tithi.
By directing the practitioner away from transient goals and toward steadiness in the eternal, it frames vrata as a devotional instrument—regular observance that trains remembrance, restraint, and reverence.
Calendar/ritual timing (tithi and lunar fortnight) is emphasized: the vow is specifically fixed on Ūrja month’s Śukla Caturthī, reflecting applied jyotiṣa-style timekeeping for dharmic rites.
