In Hinduism the concept of God is complex and depends on a particular tradition. The concept spans from absolute monism all the way to henotheism, monotheism and polytheism. In majority of traditions of Vaishnavism, He is Vishnu, God, and the text identifies this being as Krishna, sometimes referred as svayam bhagavan. The term isvara - from the root is, to have extraordinary power. Some forms of traditional sankhya systems contrast purusha (devine, or souls) to prakriti (nature or energy), however term of sovereign God, ishvara is mentioned six times in the Atharva Veda, and is central to many traditions. For Sindhi Hindus, who are deeply influenced by Sikhism, God is seen as the omnipotent cultivation of all Hindu gods and goddesses.In short the soul paramatma of all Gods and Godesses are the omnipresent Brahman and are enlightened beings.
Brahman is the eternal, unchanging, infinite, immanent, and transcendent reality which is the Divine Ground of all matter, energy, time, space, being, and everything beyond in this Universe. The nature of Brahman is described as transpersonal, personal and impersonal by different philosophical schools.
It is different from Christian vision in the sense that God as per Hinduism does not reside in heaven. At the end of the word, everything including heaven dissolves in God.
