[First Section]
[The ascetic, having attained the thirteen Samayika (introspective meditation), the four Anagara (renunciation), the Ahiṃsā (non-violence), the Ahiṃsita (non-injury), and practicing various types of austerities like the fourth to the sixth, the tenth, and the twelfth Masadharmana (monthly observances) and Masardharmana (fortnightly observances)], dwells, contemplating on the self. Then the Arhat (enlightened being) Ariṣṭanemi departs from the cities of Bāravati and the Nandana gardens, and resides in other inhabited areas.
The Bhikṣu (ascetic) Gautama approaches where the Arhat Ariṣṭanemi is, and after paying obeisance and reverence to him three times, speaks thus:
"I wish, venerable sir, with your permission, to undertake the Māsikī (monthly) Bhikṣu-pratimā (vow of asceticism) and dwell accordingly." As Skandaka (an ascetic) did, so he too practices the twelve Bhikṣu-pratimās and fully engages in the austerity called Guṇaratna (Gem of Virtues).
Just as Skandaka contemplated, so does he; just as he inquired, so does he; just as he ascended the steep path together with the Elders, so does he; [for twelve years he practices the Māsikī Saṃlekhanā (gradual reduction of food intake), until he] exhausts himself, breaks his fast, shaves his head, adopts nudity, brahmacarya (celibacy), non-bathing, non-using of a seat, non-use of a vehicle, sleeping on the ground, sleeping on a plank, non-entry into another's house, enduring praise and blame, censure, ridicule, beating, reviling, the twenty-two Parisaha (hardships) and Upaśarga (calamities) like thorns in the village - he accomplishes them, [and attains] the state of the Siddha (perfected one), Buddha (enlightened one), Mukta (liberated one), Parinirvāṇa (final liberation), and the cessation of all suffering.
This, verily, O Jambū, is the exposition of the first section of the first chapter of the first lecture of the eighth Aṃga (canonical text), as taught by the ascetic who has attained perfection.
