Do not allow the judgment of others affect you in a negative way.
Judgment can come from the ego in the form of jealousy or anger, not from the heart. The judgment is used to make others feel better about themselves at your expense.
Surround yourself with positive people who opt for happiness from within, not from others demise.
We all need healthy mirroring faces to help guide us if we start to stray from the path we desire.
A true friend will bring to our attention if we stray from our path of peace, not to serve themselves but to serve the universe as a whole.
We can then take their advice into consideration without anger, without defence and check to see if their advice is in alignment with what heart is telling us.
Happiness can not be done alone, we are social creatures who depend on each other as we are all connected.
