Query: Rehash

This book was nothing new only a rehash of previous books on TM.The author was lacking in "Technique". The title suggested he was going to give you the how to to TM; however, he obliquely suggest signing up for the TM sessions at about $1,500.00.This book was nothing but a sale's pitch to sign up for the TM course.
