Anushasana Parva, the Book of Instructions, continues and concludes the teaching Bhishma began in Shanti Parva, still lying on his bed of arrows as the winter solstice approaches, the auspicious moment he had chosen, using the boon of controlling his own death granted to him earlier in life, to finally let go. Its subjects range across gift-giving and its proper conduct, the duties owed between different classes and stages of life, the treatment of guests and Brahmins, and extended reflection on the nature of true wealth and virtue, continuing Shanti Parva's encyclopedic didactic character rather than returning to narrative action. Its most famous single passage, recited independently by devout Hindus far more often than the surrounding parva as a whole, is the Vishnu Sahasranama, a hymn of one thousand names praising Vishnu's countless attributes and forms, which Bhishma recites to Yudhishthira at Krishna's own suggestion as the single teaching most capable of freeing a person from all sorrow.
The parva closes with Bhishma's death at the chosen astrologically auspicious moment, his soul, in the epic's own account, departing visibly upward like a shooting star, bringing to an end the life of the character who has, across several books, functioned as the epic's primary voice of accumulated worldly and spiritual wisdom.
