Profound Meditation 3.0 program contains 3 tracks: track 1 begins in beta then descends into delta, tracks 2 and 3 are in delta.
As you may know, deepening into delta is a kind of slow-wave "reset" which restores the mind-body to higher brain function and improved health.
The immediate result of each meditation may seem limited to clearer vision and sharper mental acuity. But at any sleeping, waking or meditative moment, this deep-delta opening could well lead to Eureka!
