A good traveler has no fixed plans and is not intent upon arriving. A good artist lets his intuition lead him wherever it wants. A good scientist has freed himself of concepts and keeps his mind open to what is. Thus the Master is available to all people and doesn't reject anyone. He is ready to use all situations and doesn't waste anything. This is called embodying the light. What is a good man but a bad man's teacher? What is a bad man but a good man's job? If you don't understand this, you will get lost, however intelligent you are. It is the great secret.
If your virtue is especially radiant, it can be possible to open a pathway to the subtle realm and receive these celestial teachings directly from the immortals.
