The simplicity of what is needed in the world is almost laughable. It is kindness. If every person were kind and considerate, all needs would be met. All people would innately and automatically take care of others, never take for themselves, but understand that in giving to others that others will give to him or her.
All violence and aggression would cease because these, in all their forms, are forms of self-first. The idea of “mine” would disappear from the collective mind stream, thus from language and from behavior patterns. We would no longer give trinkets to people (and expect praise or thanks for doing so) but would give of ourselves flawlessly and ceaselessly.
As a result, the world would be transformed from the planet of suffering perpetuated by the Law of Karma into a world of harmony perpetuated by the same Law.
Be flawlessly kind ceaselessly.
