Some gibberish...

No one speaks gibberish. No one makes clearly incorrect statements as though they are true. People don't say, "2 + 2 = 5", or "A day lasts for 15 hours", or "Murder is the best solution for dealing with difficult people". Everything you've ever read by anyone, every sentence, contains a parenthetical ('I believe this to be true.').

All words which emanate from any human's head/mouth, are believed to be true and valid for themselves and their listeners. Regardless of content, there is a tacit acceptance by the speaker, that that very content is meaningful, pertinent.

This is a form of collusion between the speaker and the other thoughts in his head at the time, that he is conscious of at the time. In fact, the collusion is between the very thoughts themselves, and the speaker has no particular role in that.

If you read/hear something, from any source (including your own brain), where the content is deemed to be "the truth", then it is faulty.

Only that information, which points the listener back to the very receiver of that material energy (the mind), thereby turning thoughts in on themselves, is of any operational value, to one wanting to discover the truth for himself.

The best teaching is "Shut up!" "Zip it!"
Think but don't speak, Think but don't believe.
