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.
Desert Tradition

Cheyenne Indians
