Would the world be better off without religion? Yes. Because religion forces people to divide their spirituality into little tribal groups who continually fight over territory.
I mean face it.................Jews, Christians and Muslims all believe in the same God, they just fight over how to worship Him.
What Jesus taught in Israel, and what Buddha taught in India are pretty much the same lessons, only they were framed differently to speak to the people they were trying to teach. Buddha said that all people can become a Buddha if they follow the Noble 8 Fold Path. Jesus tried to teach us all that we are all a small piece of God, but we also have to follow a certain path.
What Judaic theology and Taoist philosophy teach are remarkably similar.
We don't need religion, we need spirituality, which tells us all that we need to cooperate.
Religion divides, spirituality unites. One of the best pieces of wisdom that I've ever received was from a friend of mine (who listened to my questions of which dogma to believe), told me to look for the similarities between religions rather than the differences, because I'd get much farther that way.
He was right.
I'm not a human looking for a spiritual experience, but rather I'm a spiritual being having a human experience.
