"On the internal level, the Buddha, Dhamma, and Sangha are the skillful qualities we develop in our own minds in imitation of our external models. For instance, the Buddha was a person of wisdom, purity, and compassion. When we develop wisdom, purity, and compassion in our own minds, they form our refuge on an internal level. The Buddha tasted Awakening by developing conviction, persistence, mindfulness, concentration, and discernment. When we develop these same qualities to the point of attaining Awakening too, that Awakening is our ultimate refuge. This is the point where the three aspects of the Triple Gem become one: beyond the reach of greed, anger, and delusion, and thus totally secure."
