"Next in order is the excellent Anusasana Parva. In it is described how Yudhishthira, the king of the Kurus, was reconciled to himself on hearing the exposition of duties by Bhishma, the son of Bhagirathi. This Parva treats of rules in detail and of Dharma and Artha; then the rules of charity and its merits; then the qualifications of donees, and the supreme ride-regarding gifts. This Parva also describes the ceremonials of individual duty, the rules of conduct and the matchless merit of truth. This Parva showeth the great merit of Brahmanas and kine, and unraveleth the mysteries of duties in relation to time and place. These are embodied in the excellent Parva called Anusasana of varied incidents. In this hath been described the ascension of Bhishma to Heaven. This is the thirteenth Parva which hath laid down accurately the various duties of men. The number of sections, in this is one hundred and forty-six. The number of slokas is eight thousand.
