The ritual itself uses the caster's body as payment, offering it up as a vessel to the spirit they are summoning. Generally, the spirit will be an evil spirit and usually, such things are done in a desperate need for revenge. When performing the ritual the caster is supposed to state what they wish the spirit to do. The spirit will then do those tasks and once completed obtain the body as their own. He drew the array properly but did not state what he needed. He also copied it from an incomplete page.
The array is also drawn in blood.... There was so much, that... he probably would not have lived if he had failed.
Once the ritual is finished the caster's soul leaves the mortal realm instantly. There is no lingering, it is an exchange. I'm not sure if he went back into the reincarnation cycle immediately, or... went to wherever I might have been.
As you can guess he was greatly abused and not of sound mind when he performed this....
