Most people have a hard time when they get criticized, judged or condemned. Consider these ideas the next time you get criticized (and there will be many next times!).
First remember that what people criticize in you is really something within them that they are struggling with.
So feel compassion for them. Next, take being criticized as an opportunity to have inner equanimity. Work on being the witness and observer to the criticism and do not partake in the "play of consciousness" that you are witnessing.
Lastly remember that there was never a statue raised to a critic. But every person who has a statue raised in their honor was viciously criticized, condemned and judged negatively. So, when someone talks bad about you, smile to yourself and celebrate within, as the Universe is with you always.
