Thanks! Didn't realize it was a Lojong text so didn't know where to look. I am glad Geshe la it teaching this, it will force me to learn more about the Sakya tradition which I know very little about.
This term there were two weekends on Kunzang La'mai Zhalung and in about a years time we will do Dagpo Thargyen (Jewel Ornament of Liberation), to give students a taste of the different presentations across the Tibetan schools.
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.
