Matsya Purana — Lineage of the Pitṛs
जयन्ति यान्देवगणा वैराजा इति विश्रुताः ये चैते योगविभ्रष्टाः प्राप्य लोकान्सनातनान् //
jayanti yāndevagaṇā vairājā iti viśrutāḥ ye caite yogavibhraṣṭāḥ prāpya lokānsanātanān //
Victorious indeed are those hosts of gods famed as the Vairājas; and even those who have fallen away from yoga attain the eternal worlds.
Indirectly, it emphasizes continuity of higher realms: certain divine classes (Vairājas) and “eternal worlds” persist as stable destinations for merit, even across cosmic changes like pralaya.
It underscores that disciplined spiritual practice (yoga/inner restraint) yields lasting results; even a lapse does not erase all merit—supporting the Matsya Purana’s ethic that rulers and householders should sustain dharma and self-control for higher attainments.
No direct Vastu or temple-ritual rule is stated; the takeaway is doctrinal—classification of deities and the doctrine of attaining higher lokas, which can inform ritual intent (devatā-bhāva) rather than construction technique.
