I am looking to purchase online, a cd-rom, or dvd, a relaxation
technique that involves, breathing, imagery, and guided visualtion. It
generally falls in the categories of "stress management", "yoga", or
some kind of "alternative" healing. I do not want music, of beach
scenes or anything like that. I do not want a "yogi" teaching me about
yoga and all that. I just want a staight foward voice-guided product
to help me relax my whole body/mind, so as to begin to achieve a
"Delta" brain-wave state, along the lines of entering into and
beginning meditation.

"Power Imaging is a very special guided imagery programme. Power
Imaging assumes that there exists some unconscious motive that
prevents the success you are seeking in a given area.
As such, Power Imaging is designed to assist and facilitate the
uncovering of those unconscious motives. Once uncovered, it becomes
much easier to set obsolete and/or self-limiting motives to the side
and get on with your best. Power Imaging programmes do require you to
take time out, close your eyes and put your feet up. Power Imaging
programmes are self hypnosis directed. They combine progressive
relaxation procedures, sometimes special brain wave altering sound
frequencies, hypnotic induction and deepening techniques as well as
our patented InnerTalk method. In order to use Power Imaging you must
participate in a closed eye exercise for approximately 45 minutes
every day."
