Feeling energy flows in the body is about sublimation of semen. After ejaculation I loose feeling of energy flows, and need several days for semen to accumulate before it starts to get sublimated.
I am wondering what besides physical techniques makes sexual energy to transmute, which results in feeling energy flows?
Performing easy asanas was enough for me to start feeling energy flows. But I know some persons do not feel anything, although they perform hard-to-do asanas.
Why do gymnasts NEVER feel energy flows? Although the mode in which gymnastics and asanas are practiced are so similar. Static way of performing stretches, calm breathing and attention drawn to the body are all common features. Even most postures are common.
One person performing absolutely same exercises will get an experience of energy flows, and the other will not. It means the difference is not in a physical aspect, but then in what?
