Sa Ta Na Ma is one of the movement/mudras that I like to use to calm the body and mind. This mantra truly brings you into a meditative state.
I have my sound system to present the music below by Richard Brookens 12-minutes:
SA is the beginning, infinity, the totality of everything that ever was, is or will be.
TA is life, existence and creativity that manifests from infinity.
NA is death, change and the transformation of consciousness.
MA is rebirth, regeneration and resurrection which allows us to consciously experience the joy of the infinite.
