Translation:
The living entity who falsely identifies with his body, senses, life air and mind, and who dwells within these coverings, assumes the form of his own materially conditioned qualities and work. He is designated variously in relation to the total material energy, and thus, under the strict control of supreme time, he is forced to run here and there within material existence.
Purport:
False ego, which causes the living entity to suffer material existence, is here described in detail as the illusory identification with the material body, senses, life air and mind. The word kala refers directly to the Supreme Personality of Godhead, who imposes the limiting segments of time upon the conditioned souls, keeping them tightly bound under the laws of nature. Liberation is not an impersonal experience; liberation is attainment of one’s eternal body, senses, mind and intelligence in the association of the Personality of Godhead. We can revive our eternal, liberated personality, free from the contamination of false ego, by dedicating ourselves to the loving service of the Lord in Krsna consciousness. When the pure spirit soul accepts the false ego, he must undergo material suffering. One automatically conquers the false ego by accepting oneself, in pure Krsna consciousness, to be the eternal servant of Lord Krsna.
