That white light at the end of the tunnel may be an oncoming train! You make a good point. We should not just accept things because they are on the internet, YouTube, Project Avalon, Project Camelot, Trinity Broadcasting Network, CBS, NBC, ABC, books, the Holy Bible, DVD's, lectures, etc, etc. But we want to believe. We want to be happy and have peace within. But this tends to make us gullible. Somehow we need to develop a sound methodology of what I call 'Thought Triage' with the application of cold logic and aggressive thinking...considering all possibilities from all possible angles. But this takes a lot of work...and creates a lot of emotional and spiritual trauma. In other words, an approach which elevates the process of evaluation...rather than settling on a website, or guru, or particular point of view. It's like perpetually being the smartass at the back of the room asking questions that you're not supposed to ask...and making comments which make everyone angry and upset. Take another look at Peter Finch in the 'Network' video clips on YouTube: 1.

They may be a bit off-topic...but my point is to not just accept anything anymore...just because everyone else accepts it...or some authority says so. I don't even trust myself.
