three types of learning ［三学］ ( san-gaku): Also, three disciplines. Three disciplines that Buddhist practitioners seek to master: precepts ( shīla), meditation (dhyāna), and wisdom (prajnā). These three are said to encompass all aspects of Buddhist doctrine and practice. Precepts are rules or disciplines intended to prevent error and put an end to evil in thought, word, and deed. Meditation is a practice designed to focus one’s mind and cause it to become tranquil. Wisdom rids one of illusions and enables one to realize the truth. See also meditation; prajnā; precepts.
