The Hindu Principle of Life is based on the concept of Atman, which is a Sanskrit word meaning 'SELF' or 'SOUL'. It is the belief that each individual has an eternal SOUL that is part of a greater cosmic SOUL. This principle states that all living beings are interconnected and that the ultimate goal of life is to achieve unity with the divine. The Atman is seen as the source of all knowledge and wisdom, and it is believed that by understanding and embracing the Atman, one can attain spiritual enlightenment.
