" Here the highest knowledge Is unbounded. That which gives things Their thusness cannot be delimited by things. So when we speak of ‘limits,’ we remain confined To limited things. The limit of the unlimited is called ‘fullness.’ The limitlessness of the limited is called ‘emptiness.’ Tao is the source of both. But it is itself Neither fullness nor emptiness. Tao produces both renewal and decay, But is neither renewal or decay. It causes being and non-being But is neither being nor non-being. Tao assembles and it destroys, But it is neither the Totality nor the Void. "
― Thomas Merton , The Way of Chuang Tzu (Shambhala Library)
