No one can know the state of another’s heart. We may think we can, but that knowledge is limited to God alone. As the Buddhists say “The mind is, by its nature, restless – but you are not the mind”. As long as we stay in that surf of the mind constantly tossed and turned we are beholden to the mind and our actions and thoughts and words flow out of that area. But at deeper levels the mind is quiet and we behave and think very differently and our persona becomes more understanding and compassionate. Every person has this potential. So to judge another when he/she may be in the restless mode is an error and one that perpetuates our illusion of separateness and also our dark side. To learn to “see only good” is a wonder and a great blessing.
