Branded by Spirit is an online book by El Collie on the awakening process as it unfolded for her. Since that’s where I am myself, I especially find chapter 14 – Darkness before dawn – interesting and helpful. It’s a huge relief to know that others have and do go through a similar process and she writes about it with a great deal of wisdom and insight.
Update: I have now read all the chapters, and it’s been very helpful to me. She writes with a great deal of wisdom and insight, and it’s all from her own experience, informed by informed extensive reading on the subject. I have to admit I am familiar with most of what she writes about from own experience (including much unmentioned in this blog), so although I have never thought of my own process as a kundalini process, that may be one way to describe it.
