c10.s2.t1.8

How the one âtman is expanded into the manifold universe remains a mystery, and can only be explained by illustrations. Thus in Chând. 6. 12 the teacher causes a fruit of the Nyagrodha tree (whose shoots grow downwards and strike new roots in the earth, so that a whole grove springs up from one tree), to be brought and opened, and after the student has found in it only a quite small kernel, and within this nothing at all, the teacher addresses him:—"The subtle essence, which you do not observe, my dear sir, from this subtle essence in truth this great Nyagrodha tree has sprung up. Be confident, my dear sir, whatever this subtle essence is, of which this universe is a subsistence (a 'having this as its essence,' aitadâtmyam), that is the real, that is the soul, that art thou, O S'vetaketu."
