‘We sit and become clear, free of obstructive thoughts and fear. This is the very important essence of Zen, but it does not mean that we should become like a rock or a tree. We must not make this mistake. “Never abiding in any place, yet manifesting continually.” When the sixth patriarch heard these words from the Diamond Sutra, he became deeply enlightened. We cannot say that the mind is empty and then try to guard that state of conceptualized emptiness. True emptiness does not arise from a preconceived notion of nothing at all. It is what comes forth when the mind holds on to nothing, when in each moment and in each situation we can function freely. Yet we do not move and change independently and individually; we do not act pointlessly and without meaning.’ (The Path to Bodhidharma)
