Atman hinduism
This is a major point of difference with the Buddhist doctrine of Anattawhich holds that there is no soul or self. Atman is that which one is at the deepest level of one's existence. The Brihadaranyaka Upanishad describes Atman as that in which everything exists, which is of the highest value, which permeates everything, which is the essence of all, bliss and beyond description. That Atman self, soul is indeed Brahman.
