Bura Jo Dekhan Main Chala, Bura Naa Milya Koye
Jo Munn Khoja Apnaa, To Mujhse Bura Naa Koye

TranslationI searched for the crooked, met not a single oneWhen searched myself, "I" found the crooked one

This doha deals with our perception behavior and tendencies. It has been invariably noticed that we tend to find fault with someone else for our situations and circumstances. Our "I", the ego, always tries to put blame on others. Non-awareness of our own self is the cause of this attitude. Resultantly, we find ourselves being busy in criticizing and condemning others and conveniently term them as crooked or evil.
So Kabir says that instead of finding fault and maligning others, dive deep into your own-self. Amazingly, an honest introspection will reveal that all fault lies with "me" and "my" own perceptions and attitudes. If there is any evil or crookedness, it is in "me". Correcting this and opting for a loving and compassionate attitude will change one's perceptions and the world will appear wonderful all over again.
