Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.
If the suns come down, and the moons crumble into dust, and systems after systems are hurled into annihilation, what is that to you? Stand as a rock; you are indestructible. You are the Self, the God of the universe. Say - "I am Existence Absolute, Bliss Absolute, Knowledge Absolute, I am He," and like a lion breaking its cage, break your chain and be free forever. What frightens you, what holds you down? Only ignorance and delusion; nothing else can bind you. You are the Pure One, the Ever-blessed.
