Caturvyūha, Allahabad

Caturvyūha or Chatur-vyūha, is an ancient Indian religious concept initially focusing on the four earthly emanations of the Supreme deity Nārāyaṇa, and later Vishnu. The first of these emanations is the hero-god Vāsudeva, with the other emanations being his kinsmen presented as extensions of Vāsudeva himself. From around the 1st century CE, this "Vyuha doctrine" developed out of the earlier Vīravāda cult of the Vrishni heroes, in which the five heroes Saṃkarṣaṇa, Vāsudeva, Pradyumna, Samba and Aniruddha had remained mostly human in character. Still later, around the 4th century CE, it evolved into the Avatāravāda system of incarnations of Vishnu, in which Vishnu was the primordial being and the Vrishni heroes had become his avatars. ()
