Matsya Purana — The Pushkara Manifestation
यं कालं तौ गतौ मुक्तौ ब्रह्मा तं कालमेव हि ततो घोरतमं भूयः संश्रितः परमं व्रतम् //
yaṃ kālaṃ tau gatau muktau brahmā taṃ kālameva hi tato ghoratamaṃ bhūyaḥ saṃśritaḥ paramaṃ vratam //
The very time in which those two attained release and departed—Brahmā indeed entered that very Time; thereafter, adopting an even more formidable discipline, he again undertook the supreme vow.
It frames liberation and cosmic transition in terms of Kāla (Time), implying that even Brahmā’s activity proceeds under (and into) Time—an idea often used in Purāṇic pralaya/renewal discussions.
By highlighting “parama-vrata” (supreme vow) and intensified discipline, it supports the Matsya Purana’s ethic that rightful action includes regulated vows and austerity—principles kings and householders adopt as niyama for self-mastery and dharmic governance.
Direct vāstu rules are not stated, but the verse is ritually relevant: it emphasizes vrata/tapas as a prerequisite mindset for major rites (and, by extension, temple/ritual undertakings) in Matsya Purana traditions.
