The Northen Lights album is an Alpha-Theta trip designed to help you achieve deep levels of physical and mental relaxation. It starts ramping down from 10 Hz Alpha to a deep 5.5 Hz Theta where it stays until the end of the session. This meditative music will encourage your mind to let go of concentrated thinking and open up to a world of inner exploration and deep insight. Just close you eyes and listen to the relaxing brainwave music with singing bowls sounds in the background.
