The reason is that even perfect man is limited in the imperfect garb of humanity. The human limitation covers perfection. However great, however deep, however spiritual a person is, with all his goodness, with all his inspiration and power, he remains limited. His thought, speech, word, and action are all limited. A man cannot make himself as his pupil imagines him. Imagination goes further than the progress of man; the imagination of every person is his own, and therefore one can only make one's ideal oneself.
