The β-brainwave (13~38 Hz) dominates our consciousness when awake. θ-brainwave (4~7 Hz) reflects our subconsciousness & dreaming. δ-brainwave (0.5~3 Hz) reflects our unconsciousness. The α-brainwave (8~12 Hz) plays a role of bridging our sub- & consciousness to develop our Extra Sensory Perception & Psychokinesis. The α-brainwave will be largely decreased when we are eye-opened and getting older. Meditation can help us to convert our β-brainwave to α-brainwave.
Simply saying, slow down the biorhythms of your brain.
