The Zazen I am talking about is not the learning of a meditation, it is nothing else than the Dharma of peace and happiness, the practice-realisation of total enlightenment. Zazen is the revelation of the ultimate reality. Traps and nets can never get hold of it. If you have grasped its heart, once, then you are like the dragon who dives into the water, and like the tiger, when it penetrates deeply into the mountains.
