It emphasizes that a vow is spiritually complete only when its udyāpana (formal concluding rite) is performed after the full intended duration, marking disciplined dharma and proper closure of the sādhana.
By prescribing a fixed sacred time (Dvādāśī) for the vow’s conclusion, it aligns devotional practice with Vaishnava observances where Dvādāśī is especially auspicious for completing Vishnu-centered vratas.
Kalpa and Jyotiṣa-style ritual timing: selecting the correct lunar month (Mārgaśīrṣa), fortnight (kṛṣṇa pakṣa), and tithi (Dvādāśī) for udyāpana.
