If we categorize the customary or current sciences in this world, we can divide them into three parts: physics, psychology and parapsychology. The knowledge of physics covers those activities of life that can give limited benefit to the person. The axis of thinking of such a person is matter. Such a person can never come out of the materialistic shell. The knowledge of psychology works behind the knowledge of physics. The knowledge of psychology ties together the knowledge of thought, imagination, and feeling. Parapsychology is the name of that base of knowledge that is known as “Source of Information” in spiritualism. Intellectually this agency works in the background of the subconscious mind.
