Another suggestion : maybe (I don't know if it makes sense) with a "Level 7 "track, there could be some short tracks of "mini BrainEv" or "micro BrainEv", only 5 to 10 minutes duration, that could be listen to during a break in the day (better than any coffee break !). These tracks could be a very short summary, but for people that are well trained, having achieved the 6th level, could allow to reach very quickly deep relaxation.
What do you think about it ? Nonsense or possibility ?
