The thirty-third yoga sutra states about the difference of moments and movements, involving time. As transformations of the gunas cease, time - the incessant movement of moments, stops. These deep-seated contradictions of time can only be distinguished in the later stages of emancipation. An ordinary person is not however, conscious of the moment, he cognises this movement as past, present and future. A perfected yogi dwells in the moment, never getting involved in the movements of moments. Psychological and chronological time comes to a culmination. Dwelling in the moment, the yogi perceives the seer. Nature, since time immemorial has aided consciousness and intelligence towards evolution. And, evolution always takes place in a moment, not in the movement of time.

pratiyogiuninterrupted sequences, corresponding to, related to, co-operating with, equally matched, counteracting

aparanta at the end
nirgrahyah distinctly recognisable, entirely apprehensible, entirely comprehensible
kramah regular process, course, order, series, succession

As the mutations of the gunas cease to function, time, the uninterrupted movement of moments, stops. This deconstruction of the flow of time is comprehensible only at this final stage of emancipation.

The sequence of time is related to the order of movements of the gunas of nature. Only the yogi recognises this inter-relationship and is free from gunas.

The uninterrupted succession of moments is called time. These movements of moments and the uninterrupted mutation of the gunas of nature are distinctly recognisable at the culminating point of transformation.

The average person is not aware of moments - he understands their movement as past, present and future. When moments sup away from one`s awareness, one lives in movements. Memory begins to exert its influence, and consciousness is felt at this juncture in the movements of time.

The perfect yogi lives in the moment without getting involved in movements - the movements of moments are arrested, and psychological and chronological time comes to an end. Living in the moment, the yogi sees the seer. This is evolution. Nature eternally helps the intelligence and consciousness towards evolution (parinama nityan), whereas the seer remains eternally changeless (kutastha nityan). (iv.2i refers to the Mundakopani-sad. The first bird, as seer, was called kutastha nityan as it remained steady and still; the other, as consciousness (panndma nityan) was constantly moving in the effort to reach the first one.)

Evolution takes place in a moment. Moment implies instant while movement implies time. When change comes, it arrives at once in a moment, only after a series of efforts involving movements of time. Transformation does not come without effort. As change is noticeable to an average individual, so the end transformation is distinguishable to a yogi by virtue of his pure wisdom - dharma megha samadhi. He is free from time, place and space, while others remain trammeled in this net. He is neither attracted towards nature nor disturbed by it. He is now a divine yogi. (11.18; 111.13, 15, 53)
