power of the soul, spirit fushion Options

Iv been wondering and this is just a strectch if there is such an art of mystic ability that allows a normal human to bond his spirit with that of the fiends around him the devils that are in physical form would it be possiable for a person to be able to hold the spirit within themselves and then use it when ever they want with a degree of negetive effect but still im just wondering iv seen it done is some bits of fiction and also have read in some obscure mystice works that it is possiable i would just like to hear from others and if so how to do it would not mind learning myself

I do not mean to push the bottons so to speak on your more exprinced path i mearly ask what is asked of me and try to understand it more myself i did not know the answer so i asked i could not find one so i asked and im sorry that it is an irritation to you but i would seem wiser to ask then to act and suffer later in some cases.

And as to your answer why i dont truly know i just do not see things the way others do i see them as possiablitys actions toward instinct i do not fear the result because i understand the possiable results negative as they will most likely be but to still know about somthing like that and to have it would indeed be somthing for one lifetime one like myself can not help but wonder what its like.

You cant live if you stay in the saftey zone ones whole life not all really care about just the dangers they know they are there and know that it can happen but still do it any ways call it stuipity call it what ever you like but to live truly live for one moment in time well i see nothing wrong with that.

forgive me if this seems rude i try not to sound such ways and if it makes no sense i ask again for forgivness but thanks for the answer and advice i shall study up on it some more.
