The Upanishads

pubOne.info present you this new edition. The indefinite term “That” is used in the Upanishads to designate the Invisible-Absolute, because no word or name can fully define It. A finite object, like a table or a tree, can be defined; but God, who is infinite and unbounded, cannot be expressed by finite language. Therefore the Rishis or Divine Seers, desirous not to limit the Unlimited, chose the indefinite term “That” to designate the Absolute.
