Matsya Purana — Agastya’s Origin
*ईश्वर उवाच प्रत्यूषसमये विद्वान् कुर्यादस्योदये निशि स्नानं शुक्लतिलैस्तद्वच् छुक्लमाल्याम्बरो गृही //
*īśvara uvāca pratyūṣasamaye vidvān kuryādasyodaye niśi snānaṃ śuklatilaistadvac chuklamālyāmbaro gṛhī //
Īśvara said: “At the pre-dawn hour, the wise person should perform a bath; likewise, at its rising (dawn), even if it is still night. He should bathe using white sesame seeds; and in the same manner, the householder should wear white garments and a white garland.”
This verse is not about Pralaya; it focuses on daily ritual purity—pre-dawn bathing and auspicious observance—rather than cosmic dissolution.
It gives gṛhastha-dharma style guidance: the householder should bathe at pre-dawn/dawn and adopt sāttvika markers (white clothing and garland), emphasizing discipline, purity, and auspicious conduct.
The significance is ritual (snāna-vidhi): bathing at pratyūṣa (pre-dawn) and using white sesame, along with wearing white garments/garlands—common purity markers in Purāṇic vrata practice.
