CHRIS,
Yes, it may be simply a personal preference. You may very well be right.
Or, more probably, it may be that you are not practicing NSR correctly. If you are not transcending very much, the result will be that you will not experience enjoyment and you will not get noticeable benefits in your daily life. If this is the case, we can hardly blame NSR.
NSR/USA offers email and phone/Skype
consultations to help those who need some extra support. We have had great success helping those with lackluster sessions really start enjoying their practice. You are welcome to make use of our private, in-depth consultations.
