Mbh 13.142.2b

Indeed, these forest recluses entering into woods and forests live within them as disciples, obtaining a preceptor, live with him. The performance of the rites of Homa is their duty, as also the observance of the five sacrifices. A due observance of the rules about distribution (in respect of time) of the fivefold sacrifices as laid down in the Vedas, devotion to (other) sacrifices, forming the eighth, observance of the Chaturmasya, performance of the Paurnamasya, and other sacrifices, and performance of the daily sacrifices, are the duties of these men dissociated from wives, freed from every attachment, and cleansed from every sin. Indeed, they should live even thus in the forest. The sacrificial ladle and the water-vessel are their chief wealth. They are always devoted to the three fires. Righteous in their conduct and adhering to the path of virtue, they attain to the highest end. These Munis, crowned with (ascetic) success and ever devoted to the religion of Truth, attain to the highly sacred region of Brahman or the eternal region of Soma. O auspicious goddess, I have thus recited to thee, in brief, the outlines of the religion that is followed by forest recluses and that has many practices in detail."
