1 The son of Pradyumna, and therefore Kṛṣṇa's grandson. He is one of the five heroes of the Vṛṣṇi clan. The story of how Uṣā fell in love with Aniruddha after seeing him in a dream, and how they eventually married, is told in the Viṣṇu Purāṇa.
2 According to Pāñcarātra cosmology, Aniruddha is one of the three vyūha forms (‘emanations’) of Viṣṇu (Vāsudeva). He is emanated by the Saṃkarṣaṇa form. Thirty-eight further forms or manifestations (vibhavas) emanate from the Aniruddha vyūha; these include the avatāras of later Vaiṣṇavism. The vyūha forms are differentiated for purposes of creation, and for visualization in the different stages of worship (pūjā). Vaikhānasa theology regards Aniruddha as the irreducible form of Viṣṇu, one of a total of five forms in all.
