Atman is an important concept in Hinduism, which is the oldest religion in India. Atman means 'self' or 'soul'. Hindus believe that everyone has an Atman, which is the individual spirit that lives within each of us. The Atman is a part of Brahman, the ultimate reality or source of all being, and it is the connection between our bodies and Brahman. We all have to go through a process of self-discovery in order to find our true selves, and this is what the concept of Atman is all about. The goal is to unite our individual spirit with the universal spirit so that we can truly experience oneness with the universe.
