You might want to read this story from Kaia Tingley who has studied with Bella LaVey and encouraged me to take one of her e-courses as well on self breast massage that was extremely transformative for me and released a lot of old trauma. Bella has studied with Taoist nuns, and it seems to go deeper than simply "harvesting" energy from Jade Dragons.
