If the heart is to be filled with anything, it should be love.

If the heart is to be filled with anything, it should be love. Do not hold onto malice, it wrinkles and ages the heart prematurely. When you speak to people, say only what is bright and good. Harsh words blacken the soul and cover it with soot. When interacting with the world, do so with tenderness. Roughness makes the world hostile toward us. Love, give each other kindness, love, tenderness, and smiles.
