Shikshasamucchaya

The Shikshasamucchaya (Skt. Śikṣasamuccaya) or Compendium of Training (wyl. bslab pa kun btus) presents clearly and in detail the conduct that Bodhisattvas should embrace at all times. Both Shantideva and Nagarjuna composed a Shikshasamucchaya. It is the longest of the three texts written by Shantideva, the Sutrasamucchaya being the shorter one. The Bodhicharyavatara is the middle length text, which he chose to teach at Nalanda university because it was the right length. Nagarjuna Shiksasamuccaya is not extent anymore. Nagarjuna also composed a Sutrasamucchaya (Compendium of Sutras) which can be found in the Tengyur, whereas Shantideva's has been lost.
