The earliest reference to Solipsism may be imputed to a mistaken notion of the ideas in Hindu philosophy in the Brihadaranyaka Upanishad, dated to early 1st millennium BCE. The Upanishad holds the mind to be the only god and all actions in the universe are thought to be a result of the mind assuming infinite forms. After the development of distinct schools of Indian philosophy, Advaita Vedanta and Samkhya schools are thought to have originated concepts similar to solipsism. Actually, Brihadaranyaka (1.3.) mentions 'Prana', which is what the true meaning is of the ancient Greek 'Psyche'. Again, in the 4th chapter of the Brihadaranyaka it is called 'Atma' which is described as the 'jyotih purusha'(4.3.7.). None of these ideas being translatable as Mind, it seems that the Brihadaranyaka itself bears ample testimony to the fact that Hinduism did not preach any form of solipsism.
