After studying all the different aspects of the Vedas, a brāhmaṇa who has material desires may take permission from his spiritual master and enter family life. Otherwise, if he has no material desire, he may become a vānaprastha or sannyāsī. The proper order of succession should be followed in changing from one spiritual order to the next. One who wishes to enter the household order should accept a wife who is of the same social class, who is not objectionable, and who is somewhat younger in age than he.
