It is one of the 22 Samanya Upanishads, part of the Vedanta school of Hindu philosophy literature and is attached to the Atharva Veda. The Upanishad comprises 23 verses. The Pranagnihotra Upanishad's title literally means Hotra (sacrifice) offered to the Agni (fire) of Prana (breath, life force)." The text asserts that universal soul (God) is within one's self, all Vedic gods are embodied in the human body giving one various abilities, eating is allegorically a sacrifice to the gastric fire, and life is a ceremony to the God within. The Upanishad suggests that even if one does not perform external rituals such as the Vedic Agnihotra and one lacks the knowledge of Samkhya or Yoga philosophy, one can nevertheless achieve moksha (liberation, freedom) by realizing that the God is within one's body, and the universal soul in the individual self represents the all pervading Brahman. This realization makes a person sail through all suffering and vicissitudes of life. The Upanishad in its final passages states that virtuous duty of non-violence, compassion, patience and memory unto others is an act of worship to the God within. It concludes by re-asserting that "all the gods are enclosed in this body here".
