In Dzogchen, rigpa (; Skt. vidyā; "knowledge") is knowledge of the ground. The opposite of rigpa is ma rigpa (avidyā, ignorance). A practitioner who has attained the state of rigpa and is able to rest in it continuously is called a Rigdzin or Rigma (see Vidyadhara), which may be used as a title either pre- or post-nominally.
