Hi Shanti and Bewell,
I feel heat too particularly in certain areas and I associate that with friction or blockages that the energy is trying to move through. Ever since adding in hot and cool sensations to my spinal breathing a month or two back I have noticed they happen by themselves now, especially cool on the way up.
I have to say that adding the tantric components more aggressively to my other practices has lead to a big acceleration in the expansion of ecstasy for me. I look forward to reading Yogani’s new book on the subject.
