Have you tried the SFQ Paraliminals? They're awesome. Also, have you checked out the Sonic Access program? As usual, Learning Strategies did a fantastic job on these products.

For non-LS, Kelly Howell Brain Sync audios are really good. She has guided meditations, brainwave meditations and subliminals. Here's a link to her Sacred Ground CD set, and also links to her main website and Theater of the Mind.

Another set that's very good, and definitely metaphysical/spiritual, but more expensive, is Collapsing the World by James Arthur Ray.

Kelly Howell's and James Arthur Ray products are also available on Amazon.

Jeffrey Thompson has Awakened Mind System and Gamma System Meditations. The Gamma Meditation is supposed to help one attain the brainwave states of Tibetan Buddist monks in deep meditation.
