So they do not know. They want freedom. In the freedom, in the name of freedom, they are becoming animals. That's all. This is the civilization. But here it is said, kovida, intelligent. Intelligent man should take up this sword to cut the knot of our attachment for this material enjoyment. What is that? Anudhyāsinā. Anu means always. Another anu means following. Anu means always, and anu means following. Following means spiritual master, or ācārya. Ācāryopāsanam. "How ācārya, how spiritual master dealing, let me follow that." Or, anu, as soon as he becomes accustomed, then anu, anukṣaṇa, always chanting. Anudhyāsinā. Asinā, asinā means by sword. Anudhyāsinā yuktāḥ, karma-bandha-nibandhana. We have to cut up this knot of karma-bandhana.
By the karma-bandhana, we are transmigrating from one soul, one body to another. This is not Darwin's theory. I am the soul. I am changing, I am selecting my body, in this life. Not that by nature there is a, I mean to say, gradual evolution. Not evolution; it is already there. This living entity simply enters a particular type of body. Actually, it enters, because . . . suppose I am doing something, my next life has to become a dog, that is my punishment. Then I'll have to enter into the womb of a dog mother, and she will give me the body of dog. Then I come out and enjoy like dog. This is the law. This is the law. Not that my body is turning.
So you can become dog; you can become God also. That is stated in the Bhagavad-gītā: yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ (BG 9.25). So you create your body at the present moment. You have got the facility, the human form of body. Now you can make your choice, whether you are going to be dog or whether you are going to be god. Both. Mad-yājino 'pi yānti mām: "Those who are devotees engaged in My devotional service, they come to Me." And when you go to God, you must have a body like God. Just like if you want to enter into the water, then you must have a body like a fish. Otherwise you cannot enter into the water. Similarly, when you enter the spiritual world, then you have a body like God. And if you don't want—if you want to enjoy unrestricted sense—then you take the body of a hog.
So nature is open to everyone. You can select your own. Not that you are forced. You can have your . . . therefore it is said kovida: one must be intelligent to select, "What is my next life? How I can get out of?" That is the whole instruction of the Vedas, how we can get out of these clutches of karma-bandhana, the knot of karma, one after another.
