When he perceives that the diversified ‘modes of existence’ of all beings as men, divinities etc., are founded on the two principles of Prakrti and Purusha; when he perceives that their existence as divine, human, short, tall etc., is rooted in ‘one’ common foundation, namely, in the Prakrti, and not in the self; when he sees that ‘their expansion’, i.e., the successive proliferation into sons, grandsons and such varieties of beings, is from Prakrti alone—then he reaches the brahman. The meaning is that he attains the self devoid of limitations, in Its pure form of knowledge.
