Nectar Drops from Srila Prabhupada
"There are four divisions of human society according to Vedic literature: the brahmacārī, the gṛhastha, the vānaprastha and the sannyāsa. The brahmacārī means the student life, more or less, student life. And gṛhastha means those who are leading family life, after the student life. And vānaprastha means retired life. And the sannyāsa means renounced order. They have no connection with worldly activities. So these are four different stages of human social order."
