Buddha was the title of Gautama. He was called Buddha because his spirit expressed the meaning of the word Buddh. The word Buddh in Sanskrit means "reason." In the Buddhistic terminology the Spirit of Guidance is named Bodhisattva, which means the essence of reason. Reason in its essence is of a liquid form: it is the cream of intelligence. When it is crystallized, it becomes rigid. Very often intellectuality explains a knowledge formed by reasons, most of them of rigid character. The fine reason is subtle; the finer the reason, the less it can be explained in words. It is therefore that people with fine reason cannot very well put their reason into words. Reason in its essence is the depth of intelligence. The intelligence knows, not because it has learned; it knows because it knows. In this higher reason the Spirit of Guidance is conceived, and from that fountain of reason all the great Prophets have drunk.
