I have found that the more I struggle with myself, the less I need to fight with others, perhaps it is because there is no energy left to do so, but I have found this to be true. Self-knowledge, even a little, can bring about an acceptance of others that was missing before personal experience of one own weaknesses, compulsions and sins were dealt with.
How do others experience this? Do you find more inner peace when you are in touch with your own inner problems? do you find more peace in relationships?
