Six Yogas or Six Dharmas?
Peter Alan Roberts notes that the proper terminology is "six Dharmas of Nāropa", not "six yogas of Nāropa":
"Tilopa briefly described these six practices in a short verse text entitled Instructions on the Six Dharmas. In Tibet these practices became known as the six Dharmas of Nāropa. In English they became known as the six yogas of Nāropa through their being first translated in 1935 by Evans-Wentz in Tibetan Yoga and Secret Doctrines, even though Evans-Wentz only referred to them as "six doctrines," which is the equivalent of six Dharmas. The term yoga (sbyor ba) is never used for this set of practices in Tibetan, and they should not be confused with the Kālacaka tradition's group of six practices that are called yogas."Read more about this topic: Six Yogas Of Naropa
