This book creates an awareness that it is wrong to think that it may be possible for us to think about everything whatsoever, such as even "How God should have come into existence" or "How the universe should have come into existence" in the same way as our eyes can't see the ultraviolet rays, infrared rays and spatial dimensions beyond three dimensions and our ears can't sense the subsonic frequencies and the supersonic frequencies of sound waves. But in the same way as ultraviolet rays, infrared rays and spatial dimensions beyond three dimensions exist as well as subsonic frequencies and the supersonic frequencies of sound waves exist; we should not think that God and the souls may not exist since we are unable to see them.
