Materialistic life means forgetting one's constitutional position as the eternal servant of Kṛṣṇa, and this forgetfulness is especially enhanced in the gṛhastha-āśrama. In the gṛhastha-āśrama a young man accepts a young wife who is very beautiful in the beginning, but in due course of time, after giving birth to many children and becoming older and older, she demands many things from the husband to maintain the entire family. At such a time the wife becomes detestable to the very man who accepted her in her younger days. One becomes attached to the gṛhastha-āśrama for two reasons only—the wife cooks palatable dishes for the satisfaction of her husband's tongue, and she gives him sexual pleasure at night. A person attached to the gṛhastha-āśrama is always thinking of these two things—palatable food and sex enjoyment. The talks of the wife, which are enjoyed as a family recreation, and the talks of the children both attract the living entity. He thus forgets that he has to die someday and has to prepare for the next life if he wants to be put into a congenial body.
The deer in the flower garden is an allegory used by the great sage Nārada to point out to the King that the King himself is similarly entrapped by such surroundings. Actually everyone is surrounded by such a family life, which misleads one. The living entity thus forgets that he has to return home, back to Godhead. He simply becomes entangled in family life. Prahlāda Mahārāja has therefore hinted: hitvātma-pātaṁ gṛham andha-kūpaṁ vanaṁ gato yad dharim āśrayeta (SB 7.5.5). Family life is considered a blind well (andha-kūpam) into which a person falls and dies without help. Prahlāda Mahārāja recommends that while one's senses are there and one is strong enough, he should abandon the gṛhastha-āśrama and take shelter of the lotus feet of the Lord, going to the forest of Vṛndāvana. According to Vedic civilization, one has to give up family life at a certain age (the age of fifty), take vānaprastha and eventually remain alone as a sannyāsī. That is the prescribed method of Vedic civilization known as varṇāśrama-dharma. When one takes sannyāsa after enjoying family life, he pleases the Supreme Lord Viṣṇu.
One has to understand one's position in family or worldly life. That is called intelligence. One should not remain always trapped in family life to satisfy his tongue and genitals in association with a wife. In such a way, one simply spoils his life. According to Vedic civilization, it is imperative to give up the family at a certain stage, by force if necessary. Unfortunately, so-called followers of Vedic life do not give up their family even at the end of life, unless they are forced by death. There should be a thorough overhauling of the social system, and society should revert to the Vedic principles, that is, the four varṇas and the four āśramas.
