From The Sacred Path of the Warrior:
“For the warrior, the experience of 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. However, we are not 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 and beautiful heart. You are willing to open up, without resistance or shyness, and face the world. You are willing to share your heart with others.”- Chögyam Trungpa
