The secret of language is that in all different languages that we find today in the world there seems to be a central one that can be traced as the mother language of them all. No doubt it is difficult to distinguish that language as such or such, but the relation that exists between one language and another shows that the human race had only one to begin with. Many linguists have said that it was Sanskrit; there are others who say that before Sanskrit there was another language.

Historians will have different opinions, but metaphysics teaches us that there was a language that was the one language of the human race, then many others came from it. An historian cannot be an historian if he does not give a name to a certain language as being the first; for a metaphysician this does not matter. He only understands, he knows for certain that there was one language. He does not mind if he does not know its name.

When we come to that language we understand that it was much more natural than the languages we know today, which are most complicated. Take for instance the language of birds and animals. These languages are not made from grammar, they are not mechanical; they are natural expressions of their real sentiments, of their real needs. It is by that natural expression that other animals of the same kind understand the warning they give to move, the warning they give to protect themselves, to leave their places; the warning of death or danger, or of a change of climate, of storm or rain coming. They have a certain way of expressing affection, passion, wrath, anger, and yet it is not a mechanical language, it is a natural expression, a natural language.

The primitive language of mankind was a language of feeling, of natural expression, just like the primitive figures. If we trace back thousands of years we shall find that the name of every object was written in a sort of picture which suggested that object. Now that thousands of years have passed those figures and forms have changed, and the words of primitive language have changed. Yet the one who can see into life can trace back at least some forms and some sounds and words that come from the origin of the human race.

The outcome of the language which was the original language of humanity was that every word, every sound that was expressed not only conveyed a meaning to the mind of the person who said it, but created a sensation in the person who heard it, a sensation of a particular expression, of a particular feeling or sentiment.
