I was reading today about Acem Meditiation which sounds very similar to NSR
http://www.acem-meditation.org/english/method.shtml
They recommend for beginners two 30 minute sessions or one 45 minute per day.
I don't want spend much time on comparison but how is the session time determined? Many times it takes me a fair amount of the 15 minutes to get past the tremendous amount of noise and resistance thinking that occurs and to a more quite state and/or perhaps blankness. It feels like extending a bit at the end would be good. I am a beginner and am just asking questions. So just tell me to forget it and stay with what I am doing if that is appropriate.
The rest period at the end is most times for me an extension of the quite state
The sessions are going well and I look forward to them everyday
