Subsequent inquiries proved that the man had, when a child, lived among people who spoke that language and the impressions were left in his brain. These impressions remained stored up there, until through some cause the mind reacted, and illumination came, and then the man was able to speak the language. This shows that the mind alone is not sufficient, that the mind itself is an instrument in the hands of someone. In the case of that boy the mind contained that language, yet he did not know it, but later there came a time when he did. It shows that there is someone besides the mind; and when the boy was a baby, that someone did not use the power; but when the boy grew up, he took advantage of it, and used it. First, here is the body, second the mind, or instrument of thought, and third behind this mind is the Self of man. The Sanskrit word is Atman. As modern philosophers have identified thought with molecular changes in the brain, they do not know how to explain such a case, and they generally deny it. The mind is intimately connected with the brain which dies every time the body changes. The Self is the illuminator, and the mind is the instrument in Its hands, and through that instrument It gets hold of the external instrument, and thus comes perception.
