How does it happen that one experiences and perceives intuition or inspiration, and that one sees visions and gets revelations? There is the story of the Apostles who instantly knew many languages. This does not mean that they knew French or English, German or Spanish. It means that they knew the language of every soul, that every soul began to speak to them, that they began to communicate with every person. The meaning of revelation is the understanding of the language of the soul. Every soul is always speaking if one can only hear it. It is not always what one hears in the noise of the world or the voice of man; but even the silent trees and the still mountains speak to us when we are able to hear them. It is a language of vibrations, an imperceptible language, and yet a free mind can grasp it. The only explanation of it is that it is a music. For a musician music is a language that tells him something. The high and the low note, the flat and the sharp, are all expressive and all tell him something; it all has a meaning. A person who is not a student of music does not know that language. He will enjoy music but he does not know the language.
