love is the plenitude of man.
You look at a star for two reasons, because it is luminous, and because it is impenetrable.

Context

“After a life of love, an eternity of love is, in fact, an augmentation; but to increase in intensity even the ineffable felicity which love bestows on the soul even in this world, is impossible, even to God. God is the plenitude of heaven; love is the plenitude of man. You look at a star for two reasons, because it is luminous, and because it is impenetrable. You have beside you a sweeter radiance and a greater mystery, woman. All of us, whoever we may be, have our respirable beings. We lack air and we stifle. Then we die. To die for lack of love is horrible.” source
