HH Dalai Lama has said that for individual practice, it is better to use an English text.
A friend of mine actually knows HHDL's sister in India. His sister asked my friend for an English copy of the Six Session Guru Yoga as she had told HH she found it easier to understand Buddhist terminology in English than in Tibetan. So that gives some indication of how flexible HH is on this topic.
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.
