Look - it cannot be seen. It is beyond form. Listen - it cannot be heard. It is beyond sound. Grasp - it cannot be held. It is intangible. Stay with the ancient Tao - live this moment. Empty yourself of everything. Let the mind rest at peace. The ten thousand things rise and fall while the Self watches their passing. They grow and flourish and then return to the source. Returning to the source is stillness, which is the way of nature.
