c10.s5.t3.7

(1) In the deep sleep, which is an entrance into Brahman, according to Chând. 4. 3. 3, speech, eye, ear and *manas* enter into the *prâṇa*; and according to Pras'na 4, in dream-sleep the *indriyas* enter into *manas*, and both in deep sleep into the *tejas*. In the words that follow¹ the entrance of the five *bhûtas* and the five *tanmâtras* into the *âtman* is described, together with the five organs of knowledge and the five of action, and also *manas*, *buddhi*, *ahaṅkâra*, *c'ittam*, *tejas*, *prâṇa*, and the functions that belong to them. It is not expressly stated that the order of entrance corresponds to the series given from last to first, but on the analogy of other passages it is quite admissible.
