As a humanist, there's nothing more appealing to me than 'the religion of man'---the truth, integrity and honesty of the person.
He has to practise what he says, or he is a liar and traitor to himself.

Knowing how imperfect he is,  he humbles himself to be a better person but doesn't chide, denigrates or punishes himself in the fullest knowledge of his frailty as a human being.  This consciousness is not a self-indictment but rather an incentive for him to move forward to becoming a more wholesome person--he fully recognises that this is a lifelong process and that it is a journey he must take on his own, even at the cost of lonely pain and misery-
he can rely on no one as he must be his own guide and teacher-
this is a test of his own humaneness--he has to make his way through Via Dolorosa to find the salvation in his own religion.
The fetters that have held him back must be shaken off, his fears have to be dislodged, his doubts have to be cleared, his insight must be sharpened,  his dirt has to be washed off, his old clothes must be discarded,  his view of life must be larger and wider than his selfish past's and his view of people must be fair and humane, shorn of pride, blame, criticism and judgement, his faith and creed has to find its foundation on unshakeable grounds, his pursuit should be toward the sublime and beautiful and his compassion must spring from the fountain of his heart.

How hard it is to be a worthy human being!
Yet, there's a huge potential for good in everyone-
each heart has a candle to be kindled but it has been laid latent for too long and has to be brought into light in the process of self-discovery.

If and when there is light, would darkness not have altogether disappeared?
