Can we look upon God as our father?
God as a father figure in Hinduism : Brahma, Vishnu or Shiva (Three in one: Trimurti)
Brahma When Hindus think of God as a person who is responsible for creating the universe, they call him Brahma. He is shown with four heads to see in every direction. He has four arms and holds holy books. He sits on a lotus flower.
Vishnu When Hindus think of God as a person who looks after the world, they call him Vishnu. He has four arms. He holds divine weapons to destroy wicked people. When Vishnu is born on earth he is called an avatar. He comes to earth to teach people about religion and to protect good people. Two famous avatars of Vishnu are Rama and Krishna. Many Hindus worship Rama and Krishna as God.
Shiva Some Hindus like to think of God as Shiva. They like to think of God as both the creator and destroyer of the universe. Shiva is shown sitting in meditation. The river Ganges streams out from his hair and a snake is seen curled around his neck.
