Huzur Maharaj, Radhasoami Mat Prakash

 “The Sound heard internally is a Current which has originally emanated from the Supreme Being and is the means not only of concentrating the will but also of raising the spirit to the Source from which it emanates. At the time of initiation, a novice receives instructions as regards the particulars of the Shabd [Sound] of each sub-division by means of which he has to raise his spirit upwards.”
