"아트만" (Atman) is a concept in Hindu philosophy that refers to the true self or soul of an individual. It is considered eternal and unchanging, representing the essence of a person beyond physical existence. The idea of 아트만 is central to understanding one's identity and the nature of reality in Hinduism. In the context of Brahman, the ultimate reality or cosmic spirit, 아트만 is often described as being identical to Brahman. This relationship emphasizes the belief that realizing one's 아트만 leads to spiritual liberation, or moksha, freeing the individual from the cycle of birth and rebirth, known as samsara.
