Matsya Purana — Intermediate Dissolution
येन सृष्टं जगत् सर्वं सदेवासुरमानुषम् तमवेहि रजोरूपं महत् सत्त्वम् उदाहृतम् //
yena sṛṣṭaṃ jagat sarvaṃ sadevāsuramānuṣam tamavehi rajorūpaṃ mahat sattvam udāhṛtam //
Know that by which this entire universe—together with gods, asuras, and humans—has been created: it is Mahat, the Great Principle, described as the power formed of rajas, and also spoken of as sattva in its exalted aspect.
It identifies the immediate cosmogenic principle behind manifestation: the “mahat,” characterized by rajas (the activating force), through which the universe with all beings comes forth—implying that creation proceeds via guṇa-driven evolution rather than arbitrary emergence.
By grounding the world in guṇas (especially rajas as the force of activity), it implicitly validates disciplined action: a king or householder must act (rajas) but refine it with sattva—clarity, restraint, and right understanding—so governance and worldly duties align with cosmic order.
No direct Vāstu or ritual rule is stated; however, the verse supplies the metaphysical backdrop often used in Purāṇic ritual/temple contexts—creation as ordered manifestation through guṇas—supporting the idea that sacred building and worship should embody sattvic order while channeling rajasic activity into regulated form.
