Brihadaranyaka-Upanishad: Fourth Adhyaya: Third Brahmana

^163:2 In this world, while awake or dreaming; in the other world, while in deep sleep.

^163:3 The world thinks that he thinks, but in reality he does not, he only witnesses the acts of buddhi, or thought.

^164:1 There are really two sthanas or states only; the place where they meet, like the place where two villages meet, belongs to both, but it may be distinguished as a third. Dvivedaganga (p. 1141) uses a curious argument in support of the existence of another world. In early childhood, he says, our dreams consist of the impressions of a former world, later on they are filled with the impressions of our senses, and in old age they contain visions of a world to come.

^164:2 By works, by knowledge, and by remembrance of former things; see Brih. Up. IV, 4, 2.

^164:3 Dividing and separating the material, i.e. the impressions received from this world. The commentator explains matra as a portion of the impressions which are taken away into sleep. 'Destroying' he refers to the body, which in sleep becomes senseless, and 'building up' to the imaginations of dreams.

^165:1 The Madhyandinas read paurusha, as an adjective to ekahamsa, but Dvivedaganga explains paurusha as a synonym of purusha, which is the reading of the Kanvas.

^165:2 Cf. Susruta III, 7, 1.
