Would you tell it to someone?

Have you ever imagined that some mysteries have been already solved? Now, here is a document that contains some of the great questions being answered, and "unanswered"; soon you will understand what I mean.
One of the proposes of the alchemists was to find the Philosopher Stone; that stone in its solid state would turn plumb in gold; and in it's liquid state it would be the "Elixir of Immortality". Well, a famous researcher and scientist in France (I do not want to include nether the names, nor the exact places) around 1760 was looking for the same stone, because he certainly believed of it existence. In libraries he saw books about it and when he wanted to take those books outside the library, he could not. Any way, the thing is that one night this scientist was visited by a monk who brought a very small envelope with him. He put that envelope in the table and after a long talk he convinced the scientist to brink some plumb. Then with a strange "material" of his envelope the monk made from that plumb gold, and thrown the envelope into the fire. After that the monk convinced the scientist of that what he just saw, was the Philosopher Stone, and also mentioned that a secret society keep this secret and other "miracles" from the public knowledge for its own protection. That is an historical fact, of which I saw in the book "The rebellion of the Witches"; I just do not remember the name of the author.
I am sure that this kind of societies, some of them lead by religious organizations; maintain many things away from our knowledge. They of course have their reasons to do that; but for people as I, who love paranormal researching; that is not fare, because some of us can keep the secret.
That is what I mean, if you have the opportunity to know something that you should not know, but was shared with you with some conditions, keep the secret for the people who can not afford the truth. And if you think it is really important to share it any ways, never do that publicly. Do not take the responsibility of making people be confused, or search for that desperately. Consider also that there are sick and mad people that probably would not like what you have to say and it can be dangerous for you and the loved people around you. Some people make the mistake to speak too much, and they always pay the price. Look and know in what people you can trust (believe me you can count those with the fingers of one, maybe both hands), and only in them share what you need to share, making clear that it has to be kept only between you two.
I am telling all this because I already made a big mistake and do not want to see others making the same. I have a long experience about "hidden" things, and if you want some help,
you can ask for it.
