Take forgiveness for instance. It is not just a feeling. We do not feel like forgiving someone; but we can decide to do so. An action on our part to forgive the wrongdoings done to us.
Love may start as a feeling. We are attracted to someone. But eventually, loving someone else, or loving one another as a community or as a world, is a decision; an action. We decide that we will be kind to someone else no matter how obnoxious they are.
Anger is a feeling. Is it a negative feeling? There are no such things as negative and positive feelings. They are just emotions. Part of our make up. How we react to feelings is an action taken by ourselves. Sometimes anger is a justified feeling if it makes us stand-up against wrongdoings and evil. It's the action and the reasons behind it that is negative or positive. Not the feeling.
Humour is a feeling. It is a disposition which portrays our personality. Are we jovial in our attitude to life or do we spread doom and gloom wherever we go. Humour gives rise to laughter which is contagious. Laughter is a build up of pressure that starts in the abdomen and rises up the asparagus and comes out as a loud noise out of a hole in your head. From anywhere else and you're in trouble.
Humour can be a positive feeling if shared around kindly and wisely.
