This text should be available from any FPMT centre where they are studying the basic program, as it is the standard text for all the classes on the Uttaratantra topic. You might want to try writing to Chenrezig Institute in Australia, Nalanda Monastery in France, Lama Tzongkhapa Institute in Italy or Tse Chen Ling in San Francisco.
As you can see, since joining the Dharma Wheel board I have included a quote from that text in my signature. But FPMT is quite strict with copyright and I agreed to the policy when I was given the text! Otherwise I would have been happy to send it to you myself.
I am sure if you explained to them why it was important to have the text they would try to find a way to send you the copy.
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.
