Just as every action that emanates from us comes back to us as reaction,even so our actions may act on other people and theirs on us. Perhaps all of you have observed it as a fact that when persons do evil actions, they become more and more evil, and when they begin to do good, they become stronger and stronger and learn to do good at all times. This intensification of the influence of action cannot be explained on any other ground than that we can act and react upon each other. To take an illustration from physical science, when I am doing a certain action, my mind may be said to be in a certain state of vibration; all minds which are in similar circumstances will have the tendency to be affected by my mind. If there are different musical instruments tuned alike in one room, all of you may have noticed that when one is struck, the others have the tendency to vibrate so as to give the same note. So all minds that have the same tension, so to say, will be equally affected by the same thought. Of course,this influence of thought on mind will vary according to distance and other causes, but the mind is always open to affection. Suppose I am doing an evil act, my mind is in a certain state of vibration, and all minds in the universe,which are in a similar state, have the possibility of being affected by the vibration of my mind. So, when I am doing a good action, my mind is in another state of vibration; and all minds similarly strung have the possibility of being affected by my mind; and this power of mind upon mind is more or less according as the force of the tension is greater or less.
