According to Glenn Mullin, "Marpa Lotsawa seems mainly to have spoken of them as fourfold: (1) inner heat; (2) karmamudra, or sex yogas; (3) illusory body; and (4) clear light. Here three of the six-i.e., those of consciousness transference, forceful projection and the bardo yogas-are not given the status of separate "Dharmas," presumably because they are relegated to the position of auxiliary practices." Meanwhile, Milarepa seems to have classified the dharmas of Naropa as follows: (1) generation stage; (2) inner heat; (3) karmamudra; (4) introduction to the essence of the view of the ultimate nature of being; (5) the indicative clear light of the path; and (6) the indicative illusory nature, together with dream yoga.
