Prabhupāda: In this way, after many, many births, he gets this human form of life. Prāpyaṁ mānuṣyaṁ janma-paryayāt. By the graduation, gradual evolution process. This is real evolution. Not the body is changing. Body is already there. Jīva-jātiṣu. The jīva-jāti, species, are already there. There is a defect of Darwin's theory. He does not want, he does not know that the living entity is passing through different types of body. Not that the body is changing. Bodies are already there. Bhramadbhiḥ puruṣaiḥ prāpyaṁ mānuṣyaṁ janma-paryayāt. Paryayāt means chronological. What is called, one after another?
Karandhara: Sequential?
Prabhupāda: Sequential, yes. That's all right. Tad api. Tad api means that human form of life. Abhalatām, becomes spoiled. Tad api. Once missed, again come down. Circle. Circle. Just like merry-go-round. So you are sometimes very high and immediately low down. So this circle of birth and death in different species of life is going on, and this human form of life is a chance to get out of this cycle of birth and death. Is a chance. It is by nature's arrangement, by Kṛṣṇa's arrangement, that these living entities, who have come here in this material world for false happiness, material happiness, and they are entrapped in this birth and death problem, transmigrating from one type of life to another type of life... Here is a chance for the human being. And Kṛṣṇa comes to the human being, and He... "Here is a chance, Bhagavad-gītā." Kṛṣṇa gives them.
