GUSOIN rules forty legions. He answers questions concerning all things, present, past, and future, expounding all questions. He is known to reconcile friends and to bestow honors. He is very powerful and his appearance is best contained and minimized.
A circle should be drawn upon the ground and a clear crystal should be positioned in it in the darkness so as to catch the light of a candle's flame.
The following invocation should be spoken to induce the conjuration:
I conjure thee Gusoin by the eternal virtue of the highest, the one who is the beginning and ending of the circle of life, that thou Gusoin do now appear, in this crystal stone or any other instrument, at my pleasure, to me and to my fellow, gently and beautifully, in the fair form of a young lad, without hurt or damage of our bodies or souls, and do proceed to inform and show, without any guile or craftiness, all that we do desire or demand of thee to know, by the power of the highest, who shall come to judge the quick and the dead, and the world by fire, Amen.
Gusoin should continually be summoned until he shall appear. Once appeared, questions may be asked. Do not forget to discharge him at the end of the interview.
