Sutra 4.4.19

19. That which is not within change; for thus Scripture declares the abiding (of the soul).

That which is not within change, i.e. the highest Brahman which is free from all change and of an absolutely perfect and blessed nature—this, together with the manifestations of its glory, is what forms the object of consciousness for the released soul. The worlds which are subject to change thus form objects for that soul’s experience, in so far as they form part of Brahman’s manifestation. For Scripture declares that the released soul thus abides within, i.e. is conscious of the changeless highest Brahman, 'when he finds freedom from fear and an abode in that which is invisible, incorporeal, undefined, unsupported, then he obtains the fearless' (Taitt. Up. II, 7). And that the world is contained within Brahman as its manifestation is declared in the text, 'In that all the worlds abide, and no one goes beyond' (Ka. Up. II, 5, 8). The meaning of the text stating that the Released freely move in all worlds, and similar texts, therefore is only that the released soul while conscious of Brahman with its manifestations experiences also the enjoyments, lying within the sphere of change, which abide in the world of Hiraṇyagarbha and similar beings; not that it possesses the world-energies—creative, ruling, and so on—which are the distinctive attribute of the highest Lord.
