The initial difficulty of spirituality is a schizophrenia between true understanding and the sorrow of everyday life. Our enlightenment clashes with the outer impurities. That is why some novitiates withdraw into isolation. Once people gain true spiritual insight, they dispense with this split. They can live in this world and yet not be stained by it. They are the strongest and most serene swimmers of all. They act, and yet they barely disturb the water. Their actions are outwardly no different from ordinary actions, but they leave no wake.
