Dear Sebas, wondering were you got the Sanskrit from?
Stefan and me think we should start adopting the academic practice of putting a * in front of a reconstructed Sanskrit word which is not attested in any sources. It could be that Dakini Karmendrani is also found in some of the sarma tantras, but I doubt it, and so it seems highly unlikely that the name is attested since I'm not aware of any surviving Sanskrit manuscripts of Nyingma tantras.
It would be helpful if the Tibetan spelling would be included somewhere (Wylie, Unicode) for further research purpose. In many cases this gives more clues to the actual spelling in Sanskrit. Kent (talk) 00:46, 5 October 2018 (CEST)
