It took a lot of courage for Siddhartha to renounce his world for a higher vision of reality. How many in today’s materialist world with its money chasing denizens would be up to the challenge of going from riches, or its possibility, to rags? Not many I suspect.
The real challenge meets us when we finally get all the material things we always wanted, including security, then settle back and ask ourselves are we really, really happy? Chances are, like the song, Is That All There Is, made famous by Peggy Lee, with one of its more memorable lines, “then let's keep dancing,” we will eventually try to “keep dancing” or come to the realization that there is much more to life than satisfying our desire for material things and security.
When we get to this place, if we ever do, we come to a fork in the road. One road is “keep on dancing” which, at best, turns into spiritual materialism. The other road is much different. It opens up to a world that is outside and beyond nature; including the physical body. It is transcendent. This is where Buddhism actually begins. This is the road Siddhartha chose rather than to keep on dancing.
