Thanks and praise to the great Prince Sitri!
I called Sitri with a simple ritual where I drew his sigil and called on him by the names of the angel of the decan associated with him and the name of the decan itself. I offered him some whiskey and incense as part of the ritual as well.
I then asked him to teach me something he is capable of, and I gave a license to depart. I left the sigil and whiskey out and the incense burning.
I went to sit in another room and was reading an occult book. A technique I read there gave me exactly what I wanted, *before the incense had even finished burning*.
Praise Sitri for his quick teachings!
