Nepal: Statue of Lord Vishnu standing, Kathmandu Valley

Vishnu is the Supreme god in the Vaishnavite tradition of Hinduism. Smarta followers of Adi Shankara, among others, venerate Vishnu as one of the five primary forms of God. The Vishnu Sahasranama declares Vishnu as Paramatma (supreme soul) and Parameshwara (supreme God). It describes Vishnu as the All-Pervading essence of all beings, the master of -and beyond -the past, present and future, one who supports, sustains and governs the Universe and originates and develops all elements within. Vishnu governs the aspect of preservation and sustenance of the universe, so he is called 'Preserver of the Universe'. In the Puranas, Vishnu is described as having the divine colour of water filled clouds, four-armed, holding a lotus, mace, conch (shankha) and chakra (wheel). Vishnu is also described in the Bhagavad Gita as having a 'Universal Form' (Vishvarupa) which is beyond the ordinary limits of human perception or imagination.
