I've been practicing chi gung (off and on) for about 12 years and during the first year and a half or so I put in a fairly intensive daily effort. At some point during that first period I experienced the blossoming of my heart charka. Since then, I have only been able to reproduce but a hint of that first experience. My Sifu says that basically the first time is the most intense but still I wonder if I'm doing something wrong. Granted I have not been the most consistent practitioner but I would have thought that I'd have experienced it again by now.

Anybody have any advice or suggestions or insights into this situation?
