Read the first page, a few pages in between, and the last couple pages to get a grasp on what has gone on so far in the last 125 pages over the last three years. Almost three, close enough.
The question of why do it and the caution of be careful of what you wish for has been covered, many times. So has why evil. So has not going into it with an open mind, not trying hard enough, or trying to trick the spirit, or why would a spirit show up on command... ect. All this is because there are stories out there of people accidentally attracting entities. And some stories about being able to summon them.
If you think you have a suggestion like a spell, or herbs, crystals, particular types of faiths or books, meditation, medium practices, objects of communication, whatever... Use the search function within the thread before submitting your suggestion. If you have a counter argument to any of those suggestions.. Use the search function within the thread before posting your argument.
It should be noted I think... Since this thread has started, Sakari has flushed out a couple of "cursed" objects that are worthy thread reading. And he pulled off Sakarisquach without a peep from the general public.
Really, in a way, this thread has become sort of a searchable tool for all sorts of suggestions to anyone wanting to summon or banish entities, and all the arguments pro and con about doing so. Demons, ghosts, angels, wee folk, things of astral plane or other dimensions..
Snort, perhaps newbies that ask these sorts of questions and say teach me stuff or I want to learn... I'm gonna link this thread and tell them to start asking questions again after they have read the whole thing.
