Our emotional extremes rarely come out into the open.
We may go so far out of the way to nonchalantly help someone that it warmed their hearts forever. At an other time, we may have felt so disgusted at something that we wish secretly and momentarily that a perpetrator be banished from the face of this earth.
Each of us is a mix of good and evil. We know what society at large considers right and wrong. A simple check before any decisive action is “would I like it, if someone does the exact same thing to me?”
Sometimes things may get out of hand. But it is alright. The ancient Chinese had a system. They would never brand a person a liar. They would only point out that this person said a lie, on this date at that time.
Our mind must be strong and balanced. If something bad has happened, we cannot let it affect us forever. If a fly falls in milk, we throw the milk away. But if a fly falls in butter, we only scoop out a small section of it.
It is our choice, whether we let ourselves be polluted fully, or periodically purge out the muck. Butter up!
