Thanx Baba. Sometimes doubt is a good thing,Bandler said that too. I've been into BB's for 2&1/2 years now. I've used Thompson's products as well as Brainsync and downloaded BWgen,Dane Spotts, Synchronicity. I do believe BB's work. I have also have gone very deep using music with nature sounds too. Solitude's Pachelbel by the Sea is very relaxing. Entrainment is a fascinating subject.
