It is not something you need to seek through travel or even through study. It is there within your experience, the experience of living another day. Each day is your teacher. Each person you meet, each thought you have, each choice that you make. All of these events and experiences teach you. And what does it mean to be continually taught? It means that doors continually open. It means that each day, each moment, you hold a new key to a new door. The doors are opening continually. It may seem difficult and overwhelming to you, the rate at which the world changes. You feel that you have just begun to understand something and already it is gone from sight, with something new taking its place. But the human heart does not change. The human heart is deep and endless, with layers and layers to be discovered, and the journey into your own heart and that of others has been made by many before you and will be made by many more after your own journey is complete. And this key, the key to the mysteries of the human heart, is also lying in the palm of your hand.
