Delta Brain Waves
Delta brain waves are the slowest brain waves that the human mind generates, and they occur in frequencies of 4 Hz or less. Delta brainwaves dominate during deep, dreamless sleep. It is during this deepest state of complete relaxation that your body heals itself, and resets its internal clock. The delta state is a dreamless, completely unconscious sleep state that allows your body and brain to rest and repair. Without it, you could not survive! It is difficult for newcomers to meditation to experience such a deep state of relaxation during meditation. Brainwave entrainment technology, such as binaural beats, can be used to reach this extremely deep state of relaxation, but is generally not recommended for beginners, who should aim to master a lighter state of meditation before progressing to delta. The delta state is a mostly unconscious state in which most people are unaware and unresponsive to stimuli such as binaural frequencies. However, experienced meditators who have successfully mastered Theta meditation and who can maintain conscious awareness in this deep state, will benefit greatly from listening to delta frequency binaural meditation recordings. Most of the time, people wishing to enter a super deep state of delta meditation will successfully reach this state by going into a deep theta relaxation, and then allowing their mind to "drift" down into Delta while being guided by delta frequency binaural meditation audio. People who are able to meditate at this extremely deep level will sometimes describe spiritual encounters and out of body experiences. Delta relaxation is a profound state of relaxation indeed.
