"Fix your mind inwardly between the eyebrows on the shoreless lake of peace. Watch the eternal circle of rippling peace around you. The more you watch intently, the more you will feel the wavelets of peace spreading from the eyebrows to the forehead, from the forehead to the heart, and on to every cell in your body. Now the waters of peace are overflowing the banks of your body and inundating the vast territory of your mind. The flood of peace flows over the boundaries of your mind and moves on in infinite directions."
Paramahansa Yogananda
