Well, I've been practicing tantra now for a few months but never so much with meditation. Anyways, I started doing the spinal breathing exercise last night and I did it twice today, during both of my meditations. I was practicing tantra, (on my self), when I got near the point of no return. So I stand up and start thrusting my pelvis back and forward as I read was a good technique to channel the sexual energy. Oh good god. As I thrust I feel like my ears pleasurably pop and my body goes into this ectasy that leaves my face numb and mouth wide open. It has been a few minutes now since then and I still feel A-mazing. Has anyone else had anything of this sort happen to them?
