Six Doctrines of Naropa
(na ro chos drug) A system of advanced practices handed down from Naropa to the translator Marpa, who introduced them into Tibet. He in turn transmitted these practices to his students, particulary to Jetsun Milarepa. The six doctrines are: the practice of inner heat (gtum mo), the illusory body (sgyu lus), the dream state (rmi lam), the clear light or luminosity ('od gsal), the ejection of consciousness ('pho ba), and the intermediate states bar do.
Combined with the meditations of deities such as Vajrayogini/Vajravarahi or Chakrasamvara, and the system of Mahamudra they are the most important meditational practices of the various Kagyu schools.
