The Udyoga Parva (Sanskrit: उद्योग पर्व), or the Book of Effort, is the fifth of eighteen books of the Indian Epic Mahabharata. Udyoga Parva has 10 sub-books and 198 chapters.
Udyoga Parva describes the period immediately after the exile of Pandavas had ended. The Pandavas return, demand their half of the kingdom. The Kauravas refuse. The book includes the effort for peace that fails, followed by the effort to prepare for the great war - the Kurukshetra War.
Viduraniti, a theory of leadership, is embedded in Udyoga Parva (Chapters 33-40). The Sanatsujatiya, a text commented upon by Adi Shankara, is contained within the Udyoga Parva (Chapters 41-46).
This Parva (book) has 10 sub-parvas (sub-books or little books) and 198 adhyayas (sections, chapters). The following are the sub-parvas:
Udyoga Parva was composed in Sanskrit. Several translations of the book in English are available. Two translations from 19th century, now in public domain, are those by Kisari Mohan Ganguli and Manmatha Nath Dutt. The translations vary with each translator's interpretations.
Clay Sanskrit Library has published a 15 volume set of the Mahabharata which includes a translation of Udyoga Parva by Kathleen Garbutt. This translation is modern and uses an old manuscript of the Epic. The translation does not remove verses and chapters now widely believed to be spurious and smuggled into the Epic in 1st or 2nd millennium AD.
According to the Parvasangraha chapter of Adi Parva of one version of the Mahabharata, Vyasa had composed 186 sections in Udyoga Parva, with 6,698 slokas.
J. A. B. van Buitenen completed an annotated edition of Udyoga Parva, based on critically edited and least corrupted version of Mahabharata known in 1975. Debroy, in 2011, notes that updated critical edition of Udyoga Parva, with spurious and corrupted text removed, has 10 sub-books, 197 adhyayas (chapters) and 6,001 shlokas (verses). Debroy's translation of a critical edition of Udyoga Parva has been published in Volume 4 of his series.
