You're welcome, Lise.
Bokar Rinpoche's book, in particular, is great because it not only addresses issues relating to deity yoga in general, but it contains actual instructions in Chenrezig Deity Yoga, which is a practice that one can do without empowerment, and without fear. There's a reason this practice is the "gateway" deity practice in most Karma Kagyu centers throughout the world. It's safe, and is simple while at the same time being very rich, and is also effective.
You can check Amazon for all the books I listed....there's a newer version of Gyaltrul Rinpoche's book, called "Generation Stage" or something like that.....I've thumbed through it, and it's a great book.
Another great book I just thought of, and one that lays out the various stages of Creation Stage sadhana practice--i.e., refuge, generating bodhicitta, through the various stages of purification, protection circle, generating the supporting mandala, generating the deity or deities, etc., all the way through dissolution and re-appearance, is the Light of Wisdom, Vol. II. That book, although it is specifically about a specific Guru Rinpoche practice, if I recall, provides a great general outline of the various stages of a more complex Generation Stage practice, from the Nyingma point of view. Big Sarma sadhanas may differ in some respects, but the general stages are quite similar.
There's also a book called "Deity Yoga" by HH Dalai Lama, but I don't think it would be helpful for you, unless you already have some grounding in the basics of deity yoga and tantra in general--it deals with differences in visualization practices between the various levels of Tantric practice--Kriya, Charya, etc......though perhaps that's just what you're looking for, I don't know.
