The Upanishads, Part 1 (SBE01), by Max Müller, , at sacred-texts.com
1. 'Of all living things there are indeed three origins only 4, that which springs from an egg (oviparous), that which springs from a living being (viviparous), and that which springs from a germ.
2. 'That Being 5 (i. e. that which had produced fire, water, and earth) thought, let me now enter those three beings 5 (fire, water, earth) with this living
[paragraph continues] Self (gîva âtmâ) 1, and let me then reveal (develop) names and forms.
3. 'Then that Being having said, Let me make each of these three tripartite (so that fire, water, and earth should each have itself for its principal ingredient, besides an admixture of the other two) entered into those three beings (devatâ) with this living self only, and revealed names and forms.
4. 'He made each of these tripartite; and how these three beings become each of them tripartite, that learn from me now, my friend!
94:4 In the Ait. Up. four are mentioned, andaga, here ândaga, gâruga (i.e. garâyuga), here gîvaga, svedaga, and udbhigga, svedaga, born from heat, being additional. Cf. Atharva-veda I, 12, 1.
94:5 The text has devatâ, deity; here used in a very general sense. The Sat, though it has produced fire, water, and earth, has not yet obtained its wish of becoming many.
95:1 This living self is only a shadow, as it were, of the Highest Self; and as the sun, reflected in the water, does not suffer from the movement of the water, the real Self does not suffer pleasure or pain on earth, but the living self only.
