Ahirbudhnya Samhita

अहिर्बुध्न्यसंहिता

Named after Ahirbudhnya (a form of Rudra/Shiva) — a key Pancharatra text (~60 chapters). Known for its detailed treatment of Sudarshana Chakra (Vishnu's discus) as a cosmic power, Shakti theology, the Prapatti (surrender/sharanagati) doctrine, and an early synthesis of Shaiva and Vaishnava thought.
