As for Golden Flower Meditation, as suggested by J.J. Semple, you do it at the beginning by the 4:4:4:4 diaphragmatic breathing activity, breathing in, holding it, breathing out, holding it, doing for 100 days, and then you start the backwards circular movement.
However, what I found in one book (Taoist Meditation) translated by Thomas Cleary:
"Some concentrate attention on the breathing, like pumping a bellows. Some focus their minds on counting breaths, trying to take energy in without letting it out. There are a number of such patterns. They can cause dizziness, deafness, reddening of the eyes, distention of the abdomen, pain in the tendons and bones, mental fogginess, nocturnal emissions, and ocher symptoms."
p.125
So I'm confused now, is it meant that the J.J. Semple method is bad for you? Anyone tried it?
Please help if you have experience or knowledge, and I would be very thankful.
