prajnā ［般若］ (;  hannya): The wisdom that perceives the true nature of all things. Because prajnā leads to enlightenment, it is regarded as the mother or source of all Buddhas, and obtaining prajnā as the goal of Buddhist practice. Buddhism sets forth three types of learning that practitioners should aim to master: the observance of shīla (precepts), the practice of dhyāna (meditation), and the cultivation of prajnā. The Wisdom, or Prajnā, sutras, in particular, emphasize the cultivation of prajnā, or the perfection of wisdom. See also three types of learning.
