This is regarded as the second step of Brahmacharya. He should conduct himself toward the wife and son of his teacher just as toward the teacher himself. This too is counted as the second step of Brahmacharya. Bearing well in mind what his teacher has done for him, and understanding also its purpose, the disciple should think with a joyful heart: 'He has taught me and made me great.' This is the third step of Brahmacharya. A wise disciple should not pass on to another mode of life without asking his teacher for the final gift owed him; nor should he say, or even think in his mind, 'I am the one bestowing this gift.' This is the fourth step of Brahmacharya. He attains the first step — the object of Brahmacharya, namely the knowledge of Brahman — through time; the second step through the teacher's instruction; the third through the power of his own understanding; and the fourth through discussion. The learned have said that Brahmacharya consists of twelve virtues, that the practices of yoga are called its limbs, that steadfastness in yogic meditation is called its strength, and that one is crowned with success in it through the teacher's help and the understanding of the meaning of the Vedas. All the wealth that a disciple living in this way may earn should be given to the teacher. It is in this manner that the teacher attains a life worthy of praise. In the same way the disciple should behave toward the teacher's son. Living thus (in Brahmacharya), the disciple prospers in this world by every means and obtains numerous offspring and renown.
