Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
ब्रह्माणं च गुरोर्विद्याच् छुक्रस्यापि शचीपतिम् शनैश्चरस्य तु यमं राहोः कालं तथैव च //
brahmāṇaṃ ca gurorvidyāc chukrasyāpi śacīpatim śanaiścarasya tu yamaṃ rāhoḥ kālaṃ tathaiva ca //
One should know Brahmā as the presiding deity of Jupiter (Guru); Indra (the lord of Śacī) as that of Venus (Śukra); Yama as that of Saturn (Śanaiścara); and Kāla (Time/Death) likewise as that of Rāhu.
It does not narrate pralaya directly; it frames cosmic governance by linking grahas to higher deities (Brahmā, Yama, Kāla), implying Time (Kāla) and cosmic order operate through planetary agencies.
By knowing the presiding deities of grahas, a king or householder can perform appropriate graha-śānti and dharmic rites to reduce afflictions, support prosperity, and maintain social order—standard Purāṇic guidance for righteous governance and household stability.
The ritual significance is primary: it provides deity-correspondences used when choosing mantras, offerings, and worship targets in graha-śānti; it is not a Vāstu/temple-measurement rule but can guide navagraha worship placement and consecration intent.
