This 87 min program is specifically designed to be used during periods of study when mental alertness, focus, clarity and recall are important. It begins with a phase with frequencies to calm and balance the emotional state and focus the mind. Following that are a series of specific frequencies in the 6Hz to 40Hz Brainwave series for mental clarity and accelerated learning. Finally 108Hz is the frequency associated with Complete Knowledge and this runs for 5 mins before the integration phase at the end. Use this program with ear clip electrodes if possible.
