I struggled to take Rainbow Relaxation even remotely seriously when I first chose Hypnobirthing. (Ask my classmates about my reaction to "carrots.") When we found the original creator's voice grating, our wonderful instructor made new recordings in her own voice of this and several other relaxation scripts. I'm in the zone by the time I get to the bed of green mist. You do not have to be pregnant to enjoy this.
