It is very strange to see how 'illusion' has taken possession of the hearts of men while 'Reality' has no sway whatsoever. For example, racial difference is an optical illusion! It is a figment of imagination, yet how deep seated and powerful its influence! No one can deny the fact that mankind in toto are the progeny of Adam; that they are offshoots of one primal stock, yet the optical illusion has so radically misrepresented this plain truth that they have divided and subdivided themselves into so many tribes and nations. Although many intelligent men amongst them know that this racial difference is an optical illusion, yet they all confess their inability to stand firm before its uncanny, invisible power.
