Nāropa or Nadapada or Abhayakirti (Tib. ནཱ་རོ་པ་) (956-1040) was an important master in the Kagyü tradition. He was a disciple of the mahasiddha Tilopa and a teacher of Marpa the translator and many others. He is also counted among the eighty-four mahasiddhas.
- Peter Roberts gives Naropa's dates as 956-1040, and explains that the common dating of 1016-1100 is based on a literal reading of Tsangnyön Heruka's account of the life of Marpa, including visionary accounts without historical basis. See Mahamudra and Related Instructions, p. 14.
