Hinduism believes that the universe is a manifestation of the Universal Spirit, known as Brahman in the Upanishads. Brahman has become all the things and beings of the world. Thus there is perfect unity behind the diversity of the world phenomena. The differences appear only when the universe is observed through the mind and the senses alone. However, when the mind is transcended by the wise through spiritual experiences, the Universal Spirit is seen as the sole essence of all things and beings with names and forms.
