His Holiness Dalai Lama has encouraged Choden Rinpoche to pass on many of these rare lineages practices to the monks of Sera Jey. CR has transmitted a rare lineage of initiations that ended up being held by Mongolian Lamas, such as the Gelug Hevajra and others, and has also passed on the lineages of many rare tantric instructions, including regarding various practices of Lama Tsongkhapa.
I would say that over half the monks of Sera Jey have him as one of their gurus.
In order to ensure my mind never comes under the power of the self-cherishing attitude,
I must obtain control over my own mind.
Therefore, amongst all empowerments, the empowerment that gives me control over my mind is the best,
and I have received the most profound empowerment with this teaching.
