Has anyone met with the man who grants wishes?
Sometimes called the Black man
Black man as in The color black not the skin color
Yes like a dark shadow
I'd like to meet him but I'm scared but desperate.
The Black Man does not bestow material prosperity, only teaches and bestows skill or knowledge. The belief that one must forfeit one's soul to The Black Man is common, and again arises from the mistaken equation of the The Black Man to the Biblical Satan. In some tales, The Black Man doesn't bestow his gift for free, that in return for his blessing he requires 7 years of service,
One must remember that in many beliefs, there are different Men at the Crossroads or just 'Crossroad Entities'. The Crossroads are seen as the intersection of the Otherside and Our Side, where the spirits meet etc. The Man in Black people generally think of is the Devil of the Nameless Art (Traditional Witchcraft which originated from the British Isles)
As I mentioned, there are different Crossroad spirits and each of them do their own business, two examples of these Spirits are Papa Legba and Hekate.
If someone was to mention the man in black, or black man, my mind would instantly be cast back to the confessions of Isobel Gowdie and her description of the Devil. People like to separate witchcraft from working with the Devil, however, it is a very common theme in many traditions of witchcraft, both old, and new.
As Weather said, the Crossroads are seen as in intersection, there are lot of these beliefs in traditions of witchcraft. It is a between idea: areas in which you are between something are seen as sacred spaces and perfect spots (some would say portals of energy) to engage with the other side. The crossroads is a prime example of this as you are between directions, other things include door-ways, a gap in between a hedge, underground caves, the list could go on.
That is the rationale behind the idea, however, the spirit which one interacts with will differ dependent on one's intent and tradition. I don't think it is a matter of certain beings being associated with crossroads per se, but rather cross roads being associated with other-worldly beings in general.
I wouldn't call it granting wishes myself, I would say making an oath or pact, it is similar in other forms of spirit workings. As with most magical practices involving spirits, if you're scared it probably means your not prepared mentally.
Legba is the spirit of the crossroads in Vodou, but he's not a demon. I'm sure he grants advice but he's not necessarily like a genie with three wishes. If you need something, ask for it. There's nothing wrong with practicality in prayer.
Hecate is someone I use a lot
Jason Miller's books are simple and practical systems
He uses her a lot so I do to
But I want the black man aka the black ryder.
