Intense session and remarkable experiences! The drawing depictions were especially helpful. I actually tried 2 of the postures during this morning session after I read the post. The ones I did were the stomach pumps with the hands backwards and the hands on the knees. To my surprise, both resulted in an immediate arousal of kundalini into the subtle head after the locks were applied. So I will try the others mentioned and continue them in my practice if they prove effective for my psyche. 

Thank you very much for sharing. It was an overall encouraging and helpful post.
