Love shouldn't be about jealousy or anything like that. It should be about commitment and being able to trust that person. If you can't have that from the get-go, there's a problem.
What I needed most was to love and to be loved, eager to be caught. Happily I wrapped those painful bonds around me; and sure enough, I would be lashed with the red-hot pokers or jealousy, by suspicions and fear, by burst of anger and quarrels.
Whether we consider the individual, family, local, national or international level, peace must arise from inner peace. For example, making prayers for peace while continuing to harbor anger is futile. Training the mind and overcoming your anger is much more effective than mere prayer. Anger, hatred and jealousy never solve problems, only affection, concern and respect can do that.
