A recent example: A man who I've been interested in seemed to be pulling back from me. In that moment when I perceived being left, abandoned, rejected etc, instead of "doing", I just sat in my chair and felt it. I let my mind just be there, and focused on my body sensations. It's pretty cool when the feelings literally move and release...like damp heat that time, but it probably changes depending on the emotion and where it's built up in the body. So you don't really need to do anything other than just allow...
And, I've found that there is always another emotion around the corner...so I get lots of practice
Another cool little metaphysical side benefit...besides feeling better after the emotions clear, the original perceived problem then shifts too. In this case...of course the guy calls and everything is fine. Just my old stuff having an opportunity to be healed.
