The Sun My Heart (1996)
Context: Interpenetration is an important teaching, but it still suggests that things outside of one another penetrate into each other. Interbeing is a step forward. We are already inside, so we don't have to enter. In contemporary nuclear physics, people talk about implicit order and explicit order. In the explicit order, things exist outside of each other — the table outside of the flower, the sunshine outside of the cypress tree. In the implicit order, we see that they are inside each other — the sunshine inside the cypress tree. Interbeing is the implicit order. To practice mindfulness and to look deeply into the nature of things is to discover the true nature of interbeing. There we find peace and develop the strength to be in touch with everything. With this understanding, we can easily sustain the work of loving and caring for the Earth and for each other for a long time.
