 The incarnation doctrine is one of the important differences between Vaishnavism and Shaivism traditions of Hinduism.Incarnation concepts similar to "avatar" are also found in Buddhism, Christianity, and other religions.The scriptures of Sikhism include the names of numerous Hindu gods and goddesses, but it rejected the doctrine of savior incarnation and endorsed the view of Hindu Bhakti movement saints such as Namdev that formless eternal god is within the human heart and man is his own savior.
