There is an interesting and quite descriptive review of the 8 Coil Shakti feelgood session here. Its much longer than most, and the level of detail is impressive. Worth reading if you’re interested.
“I have, more than once, leaned back and simply enjoyed being alive within the last couple of weeks. It seems silly, but tears have welled up in my eyes while I am writing this. A flash of joy happened again and it’s hard to understand, but it’s beautiful. My vision blurs and I feel my chest rising and falling with each blessing of a breath. My mouth hangs slightly open and my body releases all the tension that was being saved in my muscles. The smiling feeling in my heart migrates down into my hips and up my throat and into my head. I feel slightly dizzy and warm. Light of weight and light in the darkness. The peace finds my toes and forearms. Strangely, the place where I was able to feel it readily at first – my hands – is not as pronounced in this state. I find myself wanting to tell the universe thank you when this joy comes to me. What I have found through meditation is the park that can be provoked. I don’t understand it, and I don’t understand the implications, but when I am in this peaceful state I can somehow flex this peaceful muscle and joy turns to a more pronounced bliss.”
