There is much to be said for mumbo jumbo. It allows you to impress people by sitting on your ass and doing nothing for 14 years, instead of doing hard stuff like math and science - things you flunked out on in school. It lets you exploit credulous people by telling them they will not die - their "soul" or underlying conciousness will survive to live another day (presumably back on planet earth). These same people can be bambozzled into given you money and serving you, the priestly class, night and day. All in return for spouting a little mumbo jumbo. It even sells magazine articles.
All religions are rackets to enrich and empower elites, just as wars are rackets to enrich elites. Whether it is Catholics "tithing" or Buddhist monks selling candles in temples in China in return for telling fortunes, it is all the same. We are animals living on earth for no reason at all; we are just a by-product of chemical processes. We have one life, then its over. End of story. Enjoy!
