Vishvaksena

Vishvaksena or Vishwaksena, also known as Senai Mudalvar (Sena Mudaliar) and Senadhipathi is the commander-in-chief of the army of the Hindu god Vishnu and the gate-keeper and "Chamberlain" of Vishnu's abode Vaikuntha.[2][3] Vishvaksena is worshipped before any ritual or function in some Vaishnava sects. He occupies an important place in Vaikhanasa and Pancaratra temple traditions, where often temple festivals begin with his worship and procession.
