There are so many different forms of life. That is in our presence. Before us there are so many examples. If you get a life of a tree, naked... Tree is naked. He's not ashamed to remain naked. And for ten thousand years you stand up. Wherefrom this life comes? It requires thought. Why the world is not full of one kind of forms of life? Why there are different types of life? Because different desires and nature's law. Nature's law, there is no excuse, the same thing, that if a child even touches fire, nature is not very merciful. It will burn. Similarly, at the time of death we have to think very rightly. That is required. That is human life. You have to train yourself in such a way that at the time of death you think of Kṛṣṇa.
Therefore Kṛṣṇa advises, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65), mām evaiṣyasi asaṁśayam. Asaṁśayam, without any doubt. If you want to go back to home, back to Godhead, which is known as Kṛṣṇaloka, Vaikuṇṭhaloka... Vaikuṇṭhaloka means... Kuṇṭha means this anxiety, and vaikuṇṭha... Vigata-kuṇṭha. Vigata means without. There is no more any anxiety. That is Vaikuṇṭhaloka, spiritual world. Material world is kuṇṭha. Kuṇṭha means anxiety, full of anxiety, and Vaikuṇṭha means there is no anxiety. Everything is freedom. Sac-cid-ānanda. Vaikuṇṭha life means sac-cid-ānanda. Kṛṣṇa's body is sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Not only Kṛṣṇa's body, anyone who lives in the spiritual world, his body is spiritual body, and spiritual body means sac, cit, ānanda. Sat means eternal. Spiritual body never annihilates. The material body annihilates. Every one of us, we have got now material body. It will annihilate. But in the spiritual world, when you have got spiritual body, it does not annihilate. Eternal. Eternal life. And cit means knowledge. So in this material body we have no knowledge. Even if we have got..., now imperfect knowledge, limited knowledge. But in the spiritual life you have got full knowledge. That is spiritual life. And ānanda.
Here is no ānanda. In this material world... Ānanda means pleasure, bliss, but here it is not possible. First of all, you have to die. You may manufacture some so-called ānanda, but you'll die. Now, suppose we are dancing here, and if we understand that immediately death will take place, then we shall not be able to enjoy the dancing. Immediately the anxiety will come. So here, ānanda, there is no ānanda. Why there is ānanda? This body is subjected to so many miserable condition of life. We become hungry, we become thirsty, there is death, there is fearfulness, there is enemy—so many things. If you study analytically that this body is simply meant for suffering, so where is ānanda? There is no ānanda; there is no complete knowledge; there is no eternity. Therefore it is called material. Just the opposite is spiritual life, just opposite. There is no death. Eternity. So civilization means that, the process by which we can transfer ourself from this nonpermanent life to permanent life, life of ignorance to life of knowledge, life of suffering to life of enjoyment. That is spiritual life.
So everyone, every human being, should be intelligent that "This is my position, so what is the use of living like a demon? Here is Kṛṣṇa. He says that 'You just become My devotee. You just think of Me.' " Man-manā bhava mad-bhaktaḥ. "Always think of Me," man-manāḥ, and mad-bhaktaḥ, "My devotee," mad-yājī, "worship Me," māṁ namaskuru, "offer obeisances unto Me. If you follow this principle, then," mām evaiṣyasi, "you come to Me." So why not sacrifice one life for Kṛṣṇa consciousness? So far the bodily enjoyment, especially sex enjoyment, we had in dog's life, cat's life, in beast life. So if by restricting this kind of sex life, little organized, if I can get back to home, back to Godhead and solve all the problems of life, is it not the decision of the intelligent man?
Why should I give me away to the animal life? Viṣayaḥ khalu sarvataḥ syāt. Viṣaya means the four necessities of material life. That is called viṣaya. Viṣaya, four nece... What are the four necessities? That so long we have got this material body, we have to eat. We cannot starve. That is not possible. So similarly, we have to take rest, sleeping, and similarly, we have to enjoy or give satisfaction to our senses, and similarly, we have to defend. This is called viṣaya. So śāstra says that this..., viṣayaḥ khalu sarvataḥ syāt: "In any form of life you'll get full facilities for the bodily necessities of life, full facilities." Just see the birds and bees. They have no anxiety for maintaining the body or fulfilling the necessities of life. Early in the morning they are not anxious. They dawn and they chirp and they fly to somewhere, in any tree, and the fruit is there. A little fruit, that is sufficient. And that is eating. And sleeping? Any tree, they'll sit down on the top and sleep. So eating, sleeping... And mating? The other sex is born along with the bird. At least two eggs are there, one male, one female. So he has no anxiety for sex, he has no anxiety for eating, he has no anxiety for sleeping, and defense everyone knows. All birds, beast, knows how to defend himself. The bird's on the ground, eating something, as soon as it sees some danger, immediately go up. That is his defense.
So śāstra says, therefore, that "These four necessities of life, you'll get, any form of life. Any insignificant form or very important form, it doesn't matter. You'll get all... This is arranged." You have no anxiety for that. Kṛṣṇa has given you. Just like even if you are put into the jail life, prison life, for these things government has arranged already. In the jail life there is eating, sleeping, arrangement. So for these things we should not be very much anxious. That is human life. Simply he has to see intelligently, things, how things are going on.
There are 8,400,000 forms of life. Out of that, the human forms in different status, 400,000. And eight millions, they are lower animals-birds, beast, aquatics, insects, serpents, so many. They're eight millions. The number of... You can see the number of human being. The other beings... Just like even a small ant. From your room thousands of small ants will come out. But in that room, as a human being, you cannot live more than two, three. That is the nature's way. You'll find so many sparrows, so many other birds, beast, even elephants. So they are getting their food, they are getting their sleeping accommodation, they have facility for sex life and they know how to defend.
