Christianity is...

Christanity is similar to tasting deeply of truth, eating and drinking of truth - to eat and drink on and on unto power and energy. It is like a certain spring when someone very thirsty begins to drink from it. But then, while he is drinking, someone rushes him off before he has drunk his fill. Afterward, he burns more ardently, because he has tasted the water and eagerly seeks it. So also in the spiritual life, a person tastes and partakes of the heavenly food, but while he is eating it is taken away and no one given him to eat his fill.
