Nancy,
Based on what I think are the probabilities
of success, Bruce's book w/ or w/o his
CD's is the best bet.
You see, not everyone responds to the Hemi-sync
sounds right off the bat. For some it could take
months of work. I bought the "Journeys out of the Body" CD set, but was unimpressed with
the one method fits all mentality. Also, it doesn't
have enough guidance for a novice.
Bruce's book on the other hand, teaches you
a multitude of techniques which are valuable
not just for afterlife exploration, but also
for meditation and communication with guidance.
My sense from people who used Bruce's technique, the success rate seems to be pretty
high. Maybe it has to do with the emphasis
on retrievals or maybe it has to do with breaking
down the barriers that we all set up to block
nonphysical perception.
One caveat is that Bruce's technique is not
going to directly lead to the classic OBE state. If you're after that, I'd recommend for example, the free e-book by Robert Peterson
http://www.robertpeterson.org/ - which has a whole list of techniques, some of which,
may help.
Everyone responds differently to different techniques. So don't give up hope if one
method doesn't work.
