There is a very nice verse in Cāṇakya śloka. You just see how much time was considered as valuable. By this verse, you will know. Cāṇakya Paṇḍita says . . . Cāṇakya Paṇḍita was a great politician. He was sometimes prime minister of the emperor of India. So he says, āyuṣaḥ kṣaṇa eko 'pi na labhya svarṇa-koṭibhiḥ (Cāṇakya-śloka 34). He says that "A moment time of your duration of life . . ." Moment. Not to speak of hours and days, but moment. He was considering moment to moment.
Just like today, 15th March, 1968, now it is half past seven or past seven, thirty-five. Now this 1968, seven thirty-five gone. As soon as it is, seven thirty-six, you cannot bring back that 1968, 15th March, evening seven thirty-five, again, even if you pay millions of dollars, "Please come back again." No. Finished. So Cāṇakya Paṇḍita says that, "Time is so valuable that if you pay millions of golden coins, you cannot get back even a moment."
What is lost is lost for good. Na cen nirarthakaṁ nītiḥ: "If you, such valuable time, spoil for nothing, without any profit," ca na hānis tato 'dhikā (Cāṇakya Paṇḍita), "just imagine how much you are losing, how greatly you are loser." The thing which you cannot get back by paying millions of dollars, if that is lost for nothing, how much you are losing, just imagine.
So the same thing: Prahlāda Mahārāja says that dharmān bhāgavatan, to become Kṛṣṇa conscious, or God conscious, is so important that we should not lose even a moment's time. Immediately we shall begin. Why? Durlabhaṁ mānuṣaṁ janma. Mānuṣaṁ janma (SB 7.6.1).
He says that this human form of body is very rare. It is obtained after many, many births. So modern civilization, they do not understand what is the value of this human form of life. They think that this body is meant for sense enjoyment like cats and dogs. The cats and dogs, they are also enjoying life in four principles: eating, sleeping, defending and mating.
So human form of life is not meant for spoiling like cats and dogs. Human form of life is meant for something else. And that "something else" is Kṛṣṇa conscious, or God consciousness, because without human form of life, no other body can understand what is God, what is this world, what I am, where from I have come, where I have to go. These things are meant for human life.
So he says that, "From very childhood . . ." Actually this is essential. From childhood, in the schools, in the colleges, this bhāgavata-dharma, or the occupation of Kṛṣṇa consciousness, should be introduced. This is necessary, but they do not understand. They think that this spot life is all, and this body is all, and there is no other life. Next life, they do not believe it. This is all due to ignorance. Life is eternity, and this spot life is preparation for the next life.
So Prahlāda Mahārāja says durlabhaṁ. Durlabhaṁ means very rarely obtained. Our modern anthropologists, they also admit it, that after many evolution of different species of life, this human form of life is obtained. But they do not know what it is meant for. That is answered here, Prahlāda Mahārāja. We have to pass through many millions of species of life.
