Summary of chapter 153 of the Agni Purāṇa is as follows:
The code of conduct for a student residing in the guru's house (guru-kula) is described in detail. Agni prescribes the brahmacārī's duties: Vedic study (svādhyāya), service to the guru (guru-śuśrūṣā), maintenance of the sacred fire (samidh-āhāra), begging for food (bhaikṣacarya), and strict celibacy. Prohibited behaviors include sleeping on a high bed, self-ornamentation, music, and association with women. The chapter describes how a model brahmacārī accumulates the tejas that will sustain him through the subsequent āśramas and ultimately qualifies him for mokṣa.
