The heart is but a small vessel; and yet dragons and lions are there, and there poisonous creatures and all the treasures of wickedness; rough, uneven paths are there, and gaping chasms. There likewise is God, ..the heavenly cities and the treasures of grace; all things are there.
St. Macarios of Egypt
The remembrance of death is the mother of wisdom.
Our pleasures are shallow, only our sorrows are deep.
So out of what you wrote about passion, I carried away this: We are moved by deep things, even though we are shallow.
