The first few times for me were strange too. Then after you do it a few times it gets easier and you can hold your breathe longer. The tingles become vibrations and you can focus the energy inside yourself to certain areas of the body (sometimes I like to move energy to my chakras) and you really can feel those focal points of energy while in this state. I'm up to a 5 minute breath hold after five rounds and the feeling of peace you experience while lying in complete relaxation without even having to move for breath is totally serene.

I encourage you to keep trying as anything new will seem difficult to begin with, but the benefits are tried and true. This has become an important part of my daily meditation routine and pre-hyperspace routine.
