The sting of judgement is first something we inflict on another when we harshly judge even without saying a word. We then inflict that pain on ourselves when there is nobody else to criticize.
This is where the line: ‘Judge lest ye be judged’ coles from.
If you want to have a good life and a better time with yourself, learn how to release judgement and critical perspectives. These are subtly destructive forces. And sometimes not so subtle.
If you have a truth that needs to be expressed, especially if it might sting, try to package and deliver it as consciously and with as much care as possible.
