"For this reason, if one continuously and extensively draws upon the power of the Light Realm, two things will inevitably happen—firstly, the 'personality' of that god will gradually be diluted and eroded by the infinite power."
"The god itself does not shrink or wear away, but as more and more emotionless, personality-less power flows in, the 'scale of existence' grows ever larger. It's akin to adding water to wine; the wine gradually becomes weaker... until one day, it turns into plain water without a trace of wine's flavor."
"This transformation is almost permanent and irreversible. Pouring the water back out cannot restore the original concentration of the wine. Only by killing the True God and their subordinate gods, allowing them to be reborn from the Fountain of the Light Realm, can their personality be restored."
