The experience of a sad and tender heart is what gives birth to fearlessness. Conventionally, being fearless means that you are not afraid or that, if someone hits you, you will hit him back. But we aren't talking about that street-fighter level of fearlessness. Real fearlessness is the product of tenderness. It comes from letting the world tickle your heart, your raw heart. You are willing to open up, without resistance or shyness, and face the world.
