It has been asked of the sages and thinkers of all times by the seekers after truth that they should explain the meaning of the word "soul." Some have tried to explain it, and some have given answers which are difficult for everyone to understand. About the meaning of the word soul many statements of thinkers differ, though all mystics arrive at the same understanding of the idea of the soul. As the air, by being caught in water, becomes a bubble for the moment, and as the waves of the air, being caught in a hollow vessel, become a sound, so Intelligence, being caught by the mind and body, becomes the soul. It is only a condition of the intelligence which is the soul. The intelligence in its original aspect is the essence of life, the spirit, or God. But when this intelligence is caught in an accommodation such as body and mind, its original nature of knowing then knows, and that knowing intelligence becomes consciousness.
