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 wife takes sannyāsa.
But this culture is lost. Now unless one is shot dead, he would not leave family life. (laughter) Even Mahatma Gandhi, he got independence and everything; still he would not leave. So he was shot dead. This is our position. All politicians, all big big men, they are not going to retire, stuck up. This is not civilization. When one is young, he can remain with family, wife, children, twenty-five to fifty years. That's all. No more. Give up. Then take vānaprastha. Train up yourself for becoming sannyāsī. Then take sannyāsa simply for understanding God. That is sannyāsa. You can take sannyāsa from the very beginning, but if it is not possible, at least at the fag end of your life everyone should take sannyāsa and completely devote in understanding the science of God. That is called sannyāsa.
