This bhāgavata-dharma, Kṛṣṇa consciousness, should be learned from the very beginning. Then it will be solid. By nature's way, younger generation, they capture very nicely. Yes. This question was asked by many gentlemen to me, that "Why younger generation attracted?" Because they are receptive. This is the age. So don't waste time. From the very beginning of life, when we can talk, when we can walk, learn Kṛṣṇa consciousness, chant Hare Kṛṣṇa. Life will be successful.
We are therefore opening so many gurukulas, to teach from the very beginning of life. Brahmacārī guru-kule vasan dānto guror hitam (SB 7.12.1). They should be trained up how to offer respect to guru, to superior. These things are not taught. The Vedic system is first brahmacārī, then gṛhastha. That is compulsory: brahmacārī, gṛhastha, vānaprastha, sannyāsa, four divisions. First of all he must be trained up first-class brahmacārī, up to twenty-five years. And then, if he likes, he can enter into family life. That is also up to fifty years. Naturally a person, after being trained up as brahmacārī enters family life, he cannot stay in family life for all the days. Fifty years, when his sons are grown up, say twenty years, twenty-five years, then he can retire from family life. That is called vānaprastha. The wife can remain as assistant, not for any other purpose. Then, when he is fully prepared, the wife goes to the care of elderly children and the man takes sannyāsa.
