3.60.20

nimeṣe yadi kalpaughasaṃvidaṃ parivindati .
nimeṣa eva tatkalpo bhavatyatra na saṃśayaḥ .. 20

19. [Sanskrit available] The manner in which the active intellect represents a thing in the soul, the same is imprinted in the consciousness of its own nature. (Here the Chit is said to be the intellectus agens and consciousness—Samvid—the intellectus patiens. The motion of the mind gives us the impressions of the swiftness and slowness of time).

20. [Sanskrit available] When our consciousness represents a twinkling of the eye as a Kalpa, we are led to believe a single moment an age of long duration. (As a short nap appears an age in dreaming), and (a long age as a moment as in the case of the seven sleepers of Kehef).
