As a drop of water seems to disappear completely in a big quantity of wine, even assuming the wine’s taste and color; just as red, molten iron becomes so much like fire it seems to lose its primary state; just as the air on a sunny day seems transformed into sunshine instead of being lit up; so it is necessary for the saints that all human feelings melt in a mysterious way and flow into the will of God. Otherwise, how will God be all in all if something human survives in [us]? No doubt, the substance remains though under another form, another glory, another power.
