"Secrets operate in a fine space between ubiquity and the unknown. If it is broadly revealed, its essence dissipates.Conversely, if it follows its sole steward from this plane to the next, it is unlikely to return. A good secret travels from one keeper to the next facilitated by an unspoken contract that keeps it from burning in the light, or sinking into darkness"
