Mbh 5.44.6b

Without requiring the preceptor by payment of the final gift, a wise disciple must not betake to another mode of life; nor should he say or even think of in his mind,--I make this gift. This is the fourth step of Brahmacharya. He attaineth the first step of (knowledge of Brahman which is) the object of Brahmacharya by aid of time; the second step, through the preceptor’s prelections; the third, by the power of his own understanding; and finally, the fourth, by discussion. The learned have said that Brahmacharya is constituted by the twelve virtues, the Yoga-practices are called its Angas, and perseverance in Yoga-meditation is called its Valam and one is crowned with success in this in consequence of the preceptor’s aid and the understanding of the sense of the Vedas. Whatever wealth a disciple, thus engaged, may earn, should all be given to the preceptor. It is thus that the preceptor obtaineth his highly praise-worthy livelihood. And thus also should the disciple behave towards the preceptor’s son. Thus stationed (in Brahmacharya), the disciple thriveth by all means in this world and obtaineth numerous progeny and fame. Men also from all directions shower wealth upon him; and many people come to his abode for practising Brahmacharya. It is through Brahmacharya of this kind that the celestials attained to their divinity, and sages, highly blessed and of great wisdom, have obtained the region of Brahman. It is by this that the Gandharvas and the Apsaras acquired such personal beauty, and it is through Brahmacharya that Surya riseth to make the day. As the seekers of the philosopher’s stone derive great happiness when they obtain the object of their search those mentioned above (the celestials and others), on completing their Brahmacharya, derive great happiness in consequence of being able to have whatever they desire.
