If you do not serve Kṛṣṇa, then you will have to serve māyā. That's all. But you have to serve. So in that respect, if we do not know who is the best master, then we will have to serve our senses, our lusty desires. If I do not become servant of Kṛṣṇa, then I shall become desire . . . to my lusty desires for sex life. I have to become servant. That is a fact. You cannot become master. Therefore the most intelligent person is he who knows that "Why shall I serve my lusty desires? Why not serve Kṛṣṇa?" Because I have to serve. This is intelligent.
So then again, śva-viḍ-varāha. Viḍ-varāha means the stool-eater. It has no discrimination. Anyone who is eating anything available, he is like viḍ-varāha. He has no discrimination. A human being should have discrimination. Eatable . . . everything is eatable. Stool is also eatable. Does it mean a human being should eat eatable stool? No. It is eatable for the pigs, for the hogs, not for you. Similarly, a human being who does not know what is eatable for him, he is just like this viḍ-varāha, viḍ-varāha, hog, who has no discrimination, "Oh, everything is all right. Eat. Everything is all right." That is viḍ-varāha.
And uṣṭra. Uṣṭra means camel. Camel enjoys his own blood. The camel eats thorny twigs. So the tongue is cut, and the blood comes out, and the blood is mixed up with the thorns, and he finds it very tasteful. He is tasting his own blood, and he is finding very tasteful. Similarly, everyone in this material world, he is enjoying sex life. He is enjoying his own blood, but he is thinking, "It is very good enjoyment." That is camel's enjoyment. One drop of semina is manufactured by so much blood. So unnecessarily we discharge semina means we are enjoying spending our own blood. But the camel does not know. Similarly, camel-like man does not know. Therefore he falls diseased. It is to be used only for purpose of having good children, not for enjoyment. That is false enjoyment. So therefore it has been described, camel.
And ass. Ass means fool number one, because he works very hard. He carries the washerman's load of cloth, two tons of, but not a single cloth belongs to him. Not a single cloth. And he will agree to carry so big burden. What is the profit? The profit is that the washerman will give a little morsel of grass, and he is satisfied. This rascal does not know, "I can get grass anywhere. Why shall I be employed by this washerman?" And another ass's qualification is that when he goes for sexual intercourse, the lady ass kicks on his face.
