You do not "own" anything, including knowledge.

The subtle belief that you "own" anything, your emotions... your feelings... your body... your mind... your history... your self... even your knowledge, is of course, the burden of being, simply, human - which leads to carrying the burden, which is the pain and suffering of human existence - being "encumbered".

However, that should not prohibit one from investigating the territory, just as the gut-felt realization that one does not "own" the land, certainly did not keep native americans from travelling far and wide in the land which was finally grabbed away from them, sometime after "The Big Landgrab of 1492"... ;^)

Of these things which one does not own, the mind - just that capacity to think - is the most extraordinary universe (in the Universe), man has never (hardly even) begun to investigate, let alone discover anything about (putting aside astonomers - and their simple siblings astrologers - and neuroscientists, who all know almost nothing.) Rather, mankind has spent the last 6000 years inventing soft sciences to study everything BUT the mind - psychiatrists don't study the mind, they only study "cases", they only study what other people say they remember, and call that: studying thinking. This is the same reason why people can not self remember, self observe, be constantly mindful. People think they are studying thinking (the mind and it's operations), but what they are studying is only what "the case" says is remembered. It's because they can't study themselves, they just don't know how.

This sorry condition, would be like being born as a native american, and never exploring your own land that you SAY you love and cherish and feel so much a part of. Staying at home, is the ordinary fate of humankind, coupled with the gut-felt desire to "return home". Venturing out, in that most extraordinary universe (in the Universe), is the work of, well, explorers.

(Of course, that job title, which one must self-select, does not suit most humans, anymore than Escape would suit most prisoners, upsetting as it would the safety and comfort of their homeland/cell.)

ps- even if some occasional prisoner does escape (for a moment or an hour or a day), he always refers to that "experience" as "home" (or seeing the face of God, or returning to the godhead, or other similar allusions), and he immediately wants to "return there" again, that is, he wants to go BACK TO PRISON... and, of course, he does! (go back to prison, that is.)
