along another line-a line compounded of the two impulses; no energy will be lost, but part of the force which gave the initial impulse will be used up in partially counteracting the new, and the resultant direction along which the body will move will be that neither of the first force nor of the second, but of the interplay of the two. A physicist can calculate exactly at what angle he must strike a moving body in order to cause it to move in a desired direction, and although the body itself may be beyond his immediate reach, he can send after it a force of calculated velocity to strike it at a definite angle, thus deflecting it from its previous course, and impelling it along a new line. In this there is no violation of law, no interference with law; only the utilization of law by knowledge, the bending of natural forces to accomplish the purpose of the human will. If we apply this principle to the moulding of karma, we shall readily see-apart from the fact that law is inviolable—that there is no “interference with karma”, when we modify its action by knowledge. We are using karmic force to affect karmic results, and once more we conquer Nature by obedience.
Let us now suppose that the advanced student, glancing backwards over the past, sees lines of past karma
