To answer this question, I looked up the definition of devotion. Love, loyalty, or enthusiasm for a person, activity, or cause. It also means religious worship, or observance. I am devoted to my husband, my children, my grandchildren, and my dog. My way of looking at devotion is surrendering to love.
The kind of devotion that Dudjom Rinpoche is writing about is reverence for a teacher. I’m very familiar with this from my yoga teacher training which was all encompassing. I was devoted to my teachers, and many teachers of the past like BKS Isengar, Desikachar, and others. I feel devoted to many teachers including Susan Piver who I study Buddhism with, and my teacher within to guide me on my path forward. Ultimately it’s all about love.
