The teachers of the science of Yoga, therefore, declare that religion is not only based upon the experience of ancient times, but that no man can be religious until he has the same perceptions himself. Yoga is the science which teaches us how to get these perceptions. It is not much use to talk about religion until one has felt it. Why is there so much disturbance, so much fighting and quarrelling in the name of God? There has been more bloodshed in the name of God than for any other cause, because people never went to the fountain-head; they were content only to give a mental assent to the customs of their forefathers, and wanted others to do the same. What right has a man to say he has a soul if he does not feel it, or that there is a God if he does not see Him? If there is a God we must see Him, if there is a soul we must perceive it; otherwise it is better not to believe. It is better to be an outspoken atheist than a hypocrite. The modern idea, on the one hand, with the "learned" is that religion and metaphysics and all search after a Supreme Being are futile; on the other hand, with the semi-educated, the idea seems to be that these things really have no basis; their only value consists in the fact that they furnish strong motive powers for doing good to the world. If men believe in a God, they may become good, and moral, and so make good citizens.
