How is nonself important?

Nonself says that everything is connected with everything else, and nothing is separate. Having the insight of nonself can help us suffer less and enjoy more. We only think we are separated by race and religion, but everything is interbeing, and we are what we perceive. Even our senses have no separate existence, but must "interbe" with everything else. "When we touch one thing we touch everything," and if we touch them deeply enough we touch the reality that is free from permanence, impermanence, self and nonself.
