No study of perception would be complete without considering the affect and control of brainwaves. It is a documented fact that yogis and meditator’s affect control of the output of various types of brain waves. Each type of brainwave is associated with different cognitive functions and perceptions. The basic brainwave types are alpha, theta, and beta. There are several technologies besides meditation to affect change of brain waves. Most technologies are audio and there are several audio techniques with the isochronic said to be the best.
Different brain waves areassociated with different states of perception. Deep unconscious sleep is delta wave. Theta wave is associated with creativity and dreaming and types of meditation. There are many links on the net to meditation and audio induction systems to induce different brainwave states with their corresponding different perceptions. You can spend years exploring this avenue of perception and transformation. We just want to learn enough to drive the car not know how every single atom moves to make it go.
