President Amy is a great spirit to work with. I’ve worked with him five or six times mostly on writing projects and he really helped tremendously.
As far as not trusting easily I think alot of Goetic spirits are like that because of the amount of people that use them and dump them or fail to give them the agreed on rewards.
On a side note it is my personal belief that the reason why newcomers to evocation get no results is because the spirit doesn’t know the person and doesn’t want to show up. That and failure to create a quality psychic connection with the spirit is probably the second most common reason.
In north African culture about 1,000 years ago the introduction rites were practiced where a practicioner would formally introduce a spirit to another practicioner. This way the spirit knows who the practicioner is and that he comes recommended.
I think it’s great your trying to cultivate a relationship with Amy he’s definitely worth it. Good luck.
