The Gurukula must be based on the principle of renunciation; vairagya vidya nija bhakti yogam [Cc. Madhya 6.254]. Bhakti is based on the principle of the renunciation of material desires beginning from the earliest age; kaumaram acaret prajna dharman bhagavatan iha [SB 7.6.1]. From the very beginning, a boy must be trained to perform devotional service to the Supreme Personality of Godhead, and not to be attached as the fruitive workers, the karmis, to the so-called fallible soldiers; dehapatya kalatradisu atma-sainyesu asatsv api tesam prammato nidhanam pasyanapi na pasyati [SB 2.1.4]. The karmis are attached too much to their bodies, children and wives, who are like fallible fighting soldiers who must ultimately be destroyed. Although they are sufficiently experienced, they still cannot see this.

Therefore our young men must be trained at the earliest age to not be attached to so many things like the home, family, friendship, society, and nation. To train the innocent boy to be a sense gratifier at the early age when the child is actually happy in any circumstance is the greatest violence. Therefore; brahmacari guru-kule vasan danto guror hitam [SB 7.12.1]. The brahmacari lives at the place of the spiritual master and works for the benefit of the spiritual master by begging for his maintenance, by cleaning, learning the principles of Krsna consciousness, and engaging in the process of bhagavata dharma, whereby his life will have a firm, sane foundation with which he can overcome the forces of maya by strong training in the beginning.

The karmis cannot accept this because they are too much attached to their bodies and cannot tolerate any austerities. Since they are too attached to their children they are even more insistent that the child be drowned in bodily consciousness so that he may avoid all types of austerities and enjoy life to the fullest, thereby going to hell at the earliest age; mahat sevam dvares ahur vimuktes tamo-dvaram yosita sangisangam [SB 5.5.2]. Those who associate with the mahatmas through service to them become eligible for liberation whereas those who are associating with woman or those who are too attached to woman are paving their way to hell. Therefore the school systems require so many codes and regulations so the children will not feel any inconvenience. The training is geared to producing cats and dogs who will feel quite at home in a society of sense gratification
