They are the ones who are really entitled to enjoy the beauty of music, whose spirit and soul are responsive with open centers, who make themselves as a medium of resonance of the music they hear. Therefore music touches them differently from any other person; music touches the depth of their being. Thus moved by music, they manifest different conditions, termed by Sufis hal, which means condition. Whoever among them is moved by spirit may manifest the ecstasy, which is called wajad, in the form of tears, sighs, or dance. It is therefore that those who do not understand the meaning of their dance call them howling dervishes, or dancing dervishes.
