One last note, since I mentioned the integral naked group. The theme of Wilber, bonder, and genpo roshi are essentially shortcuts through sadhana. This is pretty common in that a lot of teachers make similar claims. On the other end of the spectrum from a more classical standpoint you might like "the yoga of light" (not the one by Iyengar, the one by Hans Reicker) this is a translation of the hatha yoga pradipika. It's basically the process from the beginning of hatha yoga through raja yoga and what practice is involved. The other thing you might like is the "life of Milarepa; Tibet's greatest yogi". There is a movie of this on youtube but there's also a book that you can download in pdf off the internet. He details his practice from his early days in magic to profound sadhana. Before there was the Dali lama there was the karmapa and he was the beginning of this tradition.
