Sutra: To straighten the crooked, You must first do a harder thing. Straighten yourself. ~The Dhammapada of Gautama the Buddha. C.A. 500BC~
One has to learn to look at oneself with closed eyes, to watch silently. And don't carry any a priori prejudices. Many people have told you, "These are your faults." Don't carry those ideas with you, otherwise you will find them -- because thought is very inventive. Put aside all that has been told about you. Remember only one thing: Unless you know it on your own authority, it has no value, no meaning. So go without any prejudice -- for or against. Just go in total openness and see.
And if you love and if you know how to watch you will come across the most mysterious phenomenon: Seeing a fault is dissolving it. That is Buddha's great secret: Knowing that you are doing something wrong is enough; you can't do it anymore.
