All creation is governed by law. The ones which manifest in the outer universe, discoverable by scientists, are called natural laws. But there are subtler laws ruling the realms of consciousness which can be known only through the inner science of yoga. The hidden spiritual planes also have their natural and lawful principles of operation. It is not the physical scientist but the fully self-realized master who comprehends the true nature of matter. Thus Christ was able to restore the servant's ear after it had been severed by one of the disciples.
