A material scientist today finds out something and says, "Here is a new discovery!" Another says, "No, it is not true; here is another discovery which proves it wrong." And so it goes on; every year there are many new discoveries. Sometimes, too, one scientist does not think like another; they may belong to the same school, and yet each has his own idea which does not agree with the other man's. But when we consider the mystics and thinkers who look at life from a spiritual point of view, they all agree, be they Yogis, Sufis, Buddhists, or Christians -- it does not matter which.
