hi peterson
some questions about alpha :
1.how much trainig it would take to have stable alpha
2.as i understand meditation ,the more experienced you get , you can
go into slower mind states , according to some japanese research ?
3.about delta - don't n.f.b can help you get there while your awake ?
4.about theta - what are the dangers , aren't there ways to make
this travels safe on a personal (or at least without a shrink )
safer ? because this state has a huge potential .
same about a-t crossover .
thanks yaniv
