मार्गशुक्लचतुर्थ्यां तु वर्षं यावन्मुनीश्वरा । क्षपयेदेकभक्तेन नक्तेनाथ द्वितीयकम् ॥ ५५ ॥
mārgaśuklacaturthyāṃ tu varṣaṃ yāvanmunīśvarā | kṣapayedekabhaktena naktenātha dvitīyakam || 55 ||
O best of sages, beginning on the Caturthī (fourth lunar day) of the bright fortnight in Mārgaśīrṣa, one should keep this vow for a full year—taking only one meal by day (ekabhakta), and performing the second observance as nakta, fasting by day and eating at night.
Sanatkumara (in instruction to Narada and assembled sages)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It prescribes a disciplined year-long vrata aligned to a specific lunar tithi, emphasizing self-restraint (upavāsa) as a dharmic means to purify conduct and stabilize devotion.
By regulating food and daily routine through ekabhakta and nakta, the practitioner reduces sensory distraction and sustains steady devotional focus—an applied form of bhakti supported by vrata.
It uses tithi- and month-based timing (lunar calendar practice connected to Jyotiṣa/Vedāṅga) and specifies fasting modes (vrata-vidhi) such as ekabhakta and nakta.
