particles, then spaces, and then solid particles, and spaces again, corresponding through all the bodies; whereas in the normal condition the bodies do not match in that way, and the spaces of one come against the solid parts of the other, and so you get a block. When sounds are used, the mystical sounds called manṭras in Hinḍuism, the effect of those is to change the bodies from this condition to that, and so the forces from without can come into the man, and the forces in him may flow out to others. That is the value of it. You are able to produce mechanically a result which otherwise has to be produced by a tremendous exertion of the will; and the man of knowledge never uses more force than is necessary in order to bring about what he desires, and the Occultist--who is the wise man on many planes--he uses the easiest way always to gain his object. Hence the use of music, or manṭras, in every faith. Pythagoras used music in order to prepare his disciples to receive his teachings. The Greek and the Roman Catholic Churches use special forms of music to produce a definite effect upon the worshippers who hear them. All of you must be aware that there are some kinds of music which have the remarkable effect upon you, of lifting you higher than you can rise by your own unassisted effort. Even the songs of illiterate Christian bodies do have some effect upon them, in raising them to a higher level, although they possess little of the true quality of the manṭra. In Theosophy you find all these things dealt with scientifically--a mass of knowledge, but all growing out of the original statement that man can know God.
