I found this interesting video the other day by Tsem Tulku Rinpoche, about how to prepare for tantric initiations. Tsem Tulku is an interesting person in that he often reaches out to people who wouldn’t otherwise be interested in Dharma practice. In that sense, he fits his approach in order to connect to those people.
Many people that get involved with Tibetan Buddhism do so with expectations of getting high-level initiations and have all sorts of ideas about what its going to do for them. However, there’s often a certain amount of preparation that’s required in order to gain benefit from them. In this interesting video, he explains in general form, some practices and study that is required in order to prepare to take on higher practices. Specifically, he talks about ngondro. While teachers were often recommend their students to do ngondro in different sequences, I think the advice he gives is very good. Especially that he emphasizes that if someone can’t do the ngondro, do something equivalent, like doing Dharma work.
