I just wanted to post a link to this work I recently came across. Check out Chapter 1, The Bright Night of Kundalini; it is very interesting account of the awakening of kundalini in a man who had no previous knowledge of it. His description of both the process and his gradual discovery of what was happening, makes for a compelling read. He is quite a good writer, which makes his account more lucid and interesting than just about anything of this nature that I have read.
