Osho – The ordinary way of human beings is to overlook one’s own faults and to emphasize, magnify, others’ faults. This is the way of the ego. The ego feels very good when it sees, “Everybody has so many faults and I have none.” And the trick is: overlook your faults, magnify others’ faults, so certainly everybody looks like a monster and you look like a saint.
Buddha says: Reverse the process. If you really want to be transformed, overlook others’ faults — that is none of your business. You are nobody, you are not asked to interfere, you have no right, so why bother? But don’t overlook your own faults, because they have to be changed, overcome.
When Buddha says, LOOK TO YOUR OWN FAULTS, WHAT YOU HAVE DONE OR LEFT UNDONE, he does not mean repent if you have done something wrong; he does not mean brag, pat your own back if you have done something good. No. He simply means to look so that you can remember in the future that no wrong should be repeated, so that you can remember in the future that the good should be enlarged, enhanced, and the evil should be reduced — not for repentance but for remembrance.
That is the difference between the Christian attitude and the Buddhist attitude. The Christian remembers them to repent; hence Christianity creates great guilt. Buddhism never creates any guilt, it is not for repentance, it is for remembrance. The past is past; it is gone and gone forever — no need to worry about it. Just remember not to repeat the same mistakes again. Be more mindful.
