Matsya Purana — Saubhagya-Śayana Vow: Lalitā/Gaurī–Śiva Worship
ततः कालेन महता पुनः सर्गविधौ नृप अहंकारावृते लोके प्रधानपुरुषान्विते //
tataḥ kālena mahatā punaḥ sargavidhau nṛpa ahaṃkārāvṛte loke pradhānapuruṣānvite //
Then, after a long lapse of time, O King, when the process of creation (sarga) began again—within the world veiled by ahaṃkāra (ego) and constituted of Pradhāna (primordial Nature) together with Puruṣa (Conscious Spirit)—the unfolding of creation proceeded further.
It indicates that after a great period of time (following dissolution), creation begins again, and the manifested world unfolds within the framework of Pradhāna (Nature) and Puruṣa (Consciousness), with ahaṃkāra (ego-principle) acting as a covering/conditioning factor.
By addressing the listener as “O King,” it frames cosmic teaching as essential for rulership: understanding time-cycles and the ego’s veiling power supports humility, restraint, and dharmic governance rather than ego-driven rule.
No direct Vāstu or ritual rule is stated; the takeaway is conceptual—ritual and temple practice presuppose a cosmos that periodically dissolves and re-manifests, structured by Pradhāna–Puruṣa and conditioned by ahaṃkāra.
