It can be. It all depends on your attitude. The more you embrace the exploration of your body/mind in the different sessions- putting  your limits, realizing and understanding that the uncomfortable sensations you are experiencing are merely your resistance to old tension-  the less you will be stuck on the ‘pain’ and the more you will pass through to a different experience. As well, the charging we do with the breath, the awareness created by the body gestalt and the fine energy work will help you to release and open to the new rather than holding on to ‘stuckness’ from the past.
