Earth is not only the World. Mind also has a world.
Why human are naturally selfish, bring forth conflicts?
It is because of multiple reality effects. They do not see other side. People generally tend to live in their own world and do not like other people to enter in their world. A marriage will only be successful either husband or wife needs to adapt in other’s world. If you draw a line between, then, a marriage could run but not necessarily a love will exist truly.
Did Anyone saw Multiple Reality?
Siddhartha Buddha was not selfish, because he saw the Multiple Worlds, Multiple Reality. Yes, of course, me also.
Multiple Reality effects conflicts. So, For Peace, understand ultimate reality with a peaceful dialogue process. A dialogue is a bridge to understand other side reality because world lives in a multiple reality.
In conflicts, people hold only their sight, side as the ultimate reality, which brings conflicts. Life is about statistical weight value process before any significant output which happens at super conscious level in a billionth of a second, so quick. What is the weight value do you give it to your circumstances?
Is there ultimate reality? It is a place where everyone gets equal satisfaction state of mind. When mind achieve this state, the body naturally adapts to the mind state.
Then, what is the Satisfaction? It is also the state of mind depends on your mind state. If you are close to achieving your Reality, then, you will be more happy, and other will remain unhappy because you win. You do not necessarily care about ultimate reality, but if you care, then other side of reality people will be happy too when you win. Only in the state of closeness towards the Ultimate Reality, most people will be happy (win-win theory).
