Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
मन्यसे मायया जातं विष्णुं चापि युगे युगे आत्मनो न विनाशो ऽस्ति स्थावरान्ते ऽपि भूधर //
manyase māyayā jātaṃ viṣṇuṃ cāpi yuge yuge ātmano na vināśo 'sti sthāvarānte 'pi bhūdhara //
O steadfast one, you think that Viṣṇu is born through māyā in every age; yet the Self (ātman) is never destroyed—even at the end of all that is immovable.
It implies that even when the world reaches the end of the ‘immovable’ order (a dissolution), the ātman is not annihilated; cosmic change does not destroy the Self.
By stressing the imperishability of the Self and the cyclical nature of ages, it supports steadiness in dharma: a king or householder should act without panic in crises, grounding conduct in enduring spiritual truth rather than temporary conditions.
No direct Vāstu or ritual rule is stated; the takeaway is doctrinal—māyā and cyclical yugas frame why temples/rites are renewed across ages while the ultimate Self remains unchanged.
