This meditation is one of the classic Kundalini meditations. It will help balance the two brain hemispheres and let you come into the neutral self. The mantra used has the eight sounds of the Kundalini in it. It is a combination of earth and ether. Ra is the sun. Ma is the moon. Da is the earth. Sa is the infinity. Sa is the infinity. Say is that totality of infinity which is Thou. So Hung means I am thou. Sa Say So Hung is the ether mantra, Ra Ma Da Sa is the Earth mantra. It has an interconnection. Sa is the link word, it comes twice; it is the tide, and Sa is a reversal of the tide. Going, converting, reversing, it is a complete cycle.
