To rise above the mind and body is the most difficult thing for any man. To then rise above the mundane intellect and ideas of petty joys of life would be still more tougher. The Guru can only work through those who have surrendered all of the above. The purely material beings can never rise above the first covering(body) so leave alone the mind. Now think how Jesus rose above all these to reach His Father…. How many can even digest a simple bodily hurt or a humiliation of the mind? To be a spiritual being you have to rise above first the body, then mind, mundane intellect and lastly the ever enticing Maya!
