Well, nobody was arguing about that. Though I think this is rather formalist view, as it stands now Tibetans have mixed guruyoga even into stura practices such as lojong. So who cares?Malcolm wrote:There is no guru yoga in lower tantra.
Of course one needs an empowerment in order to practice Vajrayana in general, even Kriya tantra practice, but since the core element of guruyoga is faith I believe this practice can be done by anyone, who is interested as long as they have intention to receive the actual empowerment later on and have already received lung and instructions. Also if one has sufficient faith, they can receive the actual empowerment directly from Guru Padmasambhava while doing the practice (though that is probably pretty rare I guess).
