The transaction between Divine Spirits and humans is not absolutely fair.
First and foremost, only believers can engage in such transactions with Divine Spirits, and believers are generally fanatical and devout.
It's like fans purchasing items from their idols, the two parties in the transaction are not equal.
It seems like a mutual exchange of needs, but in reality, the Divine Spirits subtly control the believers.
As written on this stele, by sacrificing a part of oneself, one could obtain some kind of formidable power. Although it's not explicitly stated on the stele, it is still understood that even if one were to sacrifice something like their heart, the believer would not die.
To exchange an organ for tremendous power seems like a fair trade.
But in reality, once the transaction is made, the believer's everything falls into the hands of the Divine Spirit.
