Matsya Purana — The Viśokā-Saptamī Vow
एवं सम्पूज्य षष्ठ्यां तु भक्त्या सम्पूजयेद्द्विजान् सुप्त्वा संप्राश्य गोमूत्रम् उत्थाय कृतनैत्यकः //
evaṃ sampūjya ṣaṣṭhyāṃ tu bhaktyā sampūjayeddvijān suptvā saṃprāśya gomūtram utthāya kṛtanaityakaḥ //
Thus, having duly completed the worship, on the sixth day he should, with devotion, honor and worship the dvija, the twice-born (Brāhmaṇas). Having slept, he should sip (saṃprāśya) cow’s urine; then, rising, he should perform the daily obligatory rites (nitya-karman).
This verse is not about Pralaya; it prescribes vrata-ācāra—devotional honoring of Brāhmaṇas and personal purification as part of a ritual regimen.
It reflects householders’ (and rulers’ as exemplars) dharma: honoring dvijas, maintaining śauca (purity), and performing nitya-karmas after waking—core disciplines in Matsya Purana’s ethical-ritual guidance.
Ritually, it highlights Brāhmaṇa-pūjā and gomūtra as a purifier within vrata practice; there is no Vāstu/temple-architecture instruction in this specific verse.
