Prof Peter Harvey writes "Both Buddhism and Hinduism distinguish ego-related "I am, this is mine", from their respective abstract doctrines of "Anatta" and "Atman". This may have been an influence of Buddhism on Hinduism"
Wikipedia says "Upanishads state that the core of every person's self is not the body, nor the mind, nor the ego, but Atman, which means "soul" or "self". While the Upanishads recognized many things as being not-Self, they felt that a real, true Self could be found. Atman is that which one is at the deepest level of one's existence."
Could anyone tell me verses in Hinduism from Upanishads speaking of Non Self objects like Mind Body etc differentiating it from Atman? And are these words Anatma etc refered in Upanishads as Non Self?? If not then why do such words like Anatma get used in Vivekaschudlamai to differentiate between Atman and Body?
