“Music casts a direct influence on body, organs and the soul; diseases of body, organs and soul get cured by this (music). This is the explicit impact of sound which is concerned with the external use of ears.
“The other Music or Sound is internal and the way to listen to that is by focusing our attention on the internal ‘Shabda’ or Sound which is ringing within each one of us [Surat Shabda Meditation]. Sound (internal Sound) is a highly precious wealth in the life of every human being. So long as this Sound is present in a man he is alive; as soon as the Sound exits, it is the end of him.” (Baba Devi Sahab)
