I like to collect rune stones because their pretty , and crystals too, but I do think its all as a "geezer" would say "alot of hooey". To me yes people in the past have done "magic/magick" but it all comes down to , spirits , and things like psychokinesis , telepathy, precognition etc, to me those things you mentioned are either vague(like nostradamus or biblical prophecy) or the catalyst which allows us to unlock the part of our brain by "believing" in something. Much like strong belief in anything by a mass of people can make their minds open to allow them to use "greater powers" as we would say. The CIA and KGB did extensive tests on this subject and actually empirically proved it possible. The most powerful person so far though has been Sai Baba (that has been recorded and no one can argue with the fact he did what he did).
