Anushasana Parva (Sanskrit: अनुशासन पर्व), or the "Book of Instructions," is the thirteenth of eighteen books of the Indian Epic Mahabharata. It has 2 sub-books and 168 chapters. Sometimes this parva is referred to as the "Book of Precepts".
Anushasana Parva continues the theme of Shanti Parva, a discussion of duties of a ruler, the rule of law, instructions on dharma for those close to the leader. The dialogue is between Yudhishthira, Bhishma and other sages. The book debates the duties, behaviors and habits of individuals, with chapters dedicated to men and to women. Various types of marriages are mentioned and their merits compared. The parva also recites many symbolic tales and legends such as the legend of Nachiketa, as well as the death and last rites of Bhishma, the eldest member of the Kuru family.
Anushasana Parva (book) has 2 sub-parvas (sub-books or little books) and 168 adhyayas (sections, chapters). The 2 sub-books are:
The Parva starts with a visit to Bhishma, who is dying. He is surrounded by sages and rishis including Vashishta, Maitreya, Sanat Kumara, Valmiki, Kapila, Vyasadeva and Narada. As with Shanti Parva, Yudhishthira asks for counsel and Bhishma replies. It includes duties of the king, officials of a kingdom, men and women. The book dedicates several chapters to cows, their importance to household's food security, agriculture and wealth.
Chapter 149 of Anushasana Parva recites Vishnu sahasranama - a list of 1,000 names (sahasranama) of Vishnu. Included in the list of 1000 names for Vishnu are Shiva, Sharva, Sthanu, Ishana and Rudra. This synonymous listing of Shiva and Vishnu as one, in Mahabharata, has led to the theory that all gods mentioned in Vedic literature are one.
