Sattvata Samhita

सात्त्वतसंहिता

One of the oldest and most authoritative Pancharatra texts — the "first jewel" (Ratnatraya). Contains the foundational Vyuha doctrine: Vishnu manifests as four cosmic emanations — Vasudeva (Para), Sankarshana, Pradyumna, Aniruddha. Includes puja procedures, temple construction, and mantra-shastra.
