Bṛhat Pārāśara Horā Śāstra
Maharṣi Pārāśara · the foundational compendium
Pārāśara opens with cosmogony — the unfolding of unmanifest tattva through Brahmā, Viṣṇu and Maheśa into the manifest substrate of jyotiṣa. The grahas are introduced as cosmic operators issuing from the Trimūrti triad, with their colours, deities, and elemental natures. This adhyāya establishes the philosophical frame within which all subsequent technique operates.
Cosmogonic Trimūrti scheme is Tier-W provenance — labels the (R, g, k) substrate as the manifest order arising from avyakta.
