God has planned the external world in such a fashion that everything in it serves as a sign of the Higher Reality. Man has, moreover, been endowed with such capabilities as help him to read those signs and understand them. Now those who keep their natural faculties alive and, by availing of them, ponder over the things of the world, will unlock the doors of realisation within themselves. While those who allow the intellect to become sluggish will be unable to learn lessons from anything. They will see, but this will not be the seeing of realisation; they will hear, but this will not be the hearing of realisation.
