The present moment is ungraspable. It is empty of self-existence. It is a process – a process of ceaseless change. In a sense there is no present moment! If we try to grasp the stream of it, we ossify it, turning it from the present to a memory, a recollection, an abstraction, to something – rather than a fluid stream. Experiencing the present is to experience a flowing dynamic reality, forever in motion, never still.
Yet, we can be still and at peace in our experiencing of the stream of the present – if we let go of our attachment to it, giving up our desire to hold it as an object or to categorise it, label it, comment on it or judge it. This is mindful meditation or zazen.
