There are two fundamental schools of thought in Hinduism about the nature of one's unity with the Supreme Being. The first is known as Advaita Vedanta, or non-dualism. This is the belief that one's spiritual self is not separate from the Supreme Being. Giving everything over to the service of the Supreme Being is the path to moksha. One way to visualize this is to think about the human soul as a single blade of grass in a field, with the field being the soul of the Supreme Being. The blade of grass is part of the composition of the field, just as the human soul is part of the soul of the Supreme Being.
