Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
शुक्लास्ता नामतः सर्वास् त्रिंशतो घर्मसर्जनाः संबिभ्रति हि ताः सर्वा मनुष्यान्देवताः पितॄन् //
śuklāstā nāmataḥ sarvās triṃśato gharmasarjanāḥ saṃbibhrati hi tāḥ sarvā manuṣyāndevatāḥ pitṝn //
All those rays, known by name as the “Śuklā” group—thirty in number and emitters of heat—indeed sustain them all: human beings, the gods, and the pitṛs, the ancestral Manes.
It emphasizes maintenance rather than dissolution: the heat-emitting solar powers (rays) are described as sustaining humans, gods, and ancestors—i.e., the ongoing support of cosmic order that would cease or withdraw during Pralaya.
By linking devas and pitṛs with human life, it supports the householder-kingly duty of sustaining ṛta/dharma through yajña and śrāddha—acts that honor devas and ancestors and keep society aligned with the sustaining cosmic forces.
Ritually, it frames solar heat as a sustaining principle relevant to calendrical observances and offerings to devas and pitṛs; in Vastu-oriented readings, it underlines why solar direction, light, and heat are treated as foundational considerations in sacred planning and ritual timing.
