(Srila Prabhupada in Montreal, 1968)
Devotee: The Bhagavad-gītā has stated that whatever one's consciousness is during his lifetime will be at the time of his death, and that will determine his next body. Now, one who is living very lustily during his lifetime, his mind will be on that body.
Prabhupāda: Yes. So there are many varieties of life. Just like somebody is very lusty, and he wants sex enjoyment so many times a day. So there are many animals, many birds. They are given the opportunity like that. Just like the pigeons, the sparrows. Or there are many birds, the swans, the ducks. They have got every day twenty times, sex intercourse. So this facility is given to them. You see? Similarly, somebody wants to eat meats and blood. He is given the chance to become a tiger. So Kṛṣṇa is giving chance everyone. And one who is very dull, cannot understand simply, oh, the sense gratification, they are made the dullest possible, like trees, stand up for thousands of years.
So all these different varieties of life, eight million four-hundred-thousands, we have got different varieties. You can calculate. There are three qualities. Three into three equal to nine. Three multiplied by three becomes nine, and nine multiplied by nine becomes eighty-one. Automatically it becomes more than so many, eight million.
So God's kingdom, His calculation, His fine judgement, is very difficult to understand. But practically we see there are so many varieties of life. Why? They have been given chance: "All right, you want this sort of life? Here it is. Take it. Accept it." So they are transmigrating from one life to another, one life to another, one life to another. Out of many such millions of living entities, one who comes under Kṛṣṇa consciousness by the grace of Kṛṣṇa and His devotee, spiritual master, his life is successful. He gets the clue to get out of this entanglement. Otherwise he is to travel within these 8,400,000 species of life.
So Kṛṣṇa is giving chance, whatever you want, but He is talking also the ultimate goal of life. Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja: (BG 18.66). "You give up this searching out of your happiness in your own way, by transmigrating from one kind of life to another, one position to another. You just take shelter of Me, and I take charge of you." This is the whole proposition of Bhagavad-gītā. This is Kṛṣṇa consciousness. One has to give up searching out of happiness according to his own plan, but he has to submit himself to Kṛṣṇa, who will take charge and He will give you all happiness that you desire. That is Kṛṣṇa consciousness.
