How can I practice being non-judgmental?
The first thing is to be aware of being judgmental when it is happening. Notice how your body feels. Does your body feel open, relaxed, loving and compassionate? That feeling is only available when you are non-judgmental.
Understand that when you are judging someone or something, you are assuming that you know everything there is to know to pass judgment, and that is impossible. So recognize that you really can’t know everything there is to know and therefore you are not in a position to judge anyone. Just being aware of this relaxes you, frees you up and permits you to be open and compassionate.
