This human form, or the facility of this human form of life, which was given to us by grace of God or by the mercy of material nature, Prahlāda Mahārāja says that "Don't misuse it. Don't misuse it like animals, simply eating, sleeping and mating and defending." Durlabhaṁ mānuṣaṁ janma (SB 7.6.1). Don't be assured that your next life is going again to be a human form of life. It may be . . . there are 8,400,000 species of life, and according to my work I may enter into any type of body. Durlabhaṁ.
Therefore this rare opportunity that we have got this human form of life, mānuṣaṁ durlabhaṁ janma . . . durlabhaṁ mānuṣaṁ janma tad apy adhruvam. And it will not exist for very long time. But if you utilize it properly, then you can achieve the greatest boon. What is that? Kṛṣṇa consciousness. You can achieve the greatest boon. So Prahlāda Mahārāja is recommending that, "From the very childhood, my dear friends, you learn what is God consciousness or Kṛṣṇa consciousness. Otherwise, if you advance in age, then you'll be more complicated, more complicated."
Actually, we are experiencing. We have got about eight branches of our this movement. Not only this movement, any movement. Generally, these youngsters, they are being attracted. Any nice movement started, the youngsters, they become more attracted. Not the, I mean to say, elderly people. Because elderly people, whatever they have understood, it takes to forget for some time. But if they try they can also understand. But Prahlāda Mahārāja is recommending that before growing very old, from the childhood, receptive state, one should learn this Kṛṣṇa consciousness.
