Nothing is worth grasping at or clinging to. There is nothing that we should want to get, to have or to be. Nothing is worth getting or having. Nothing is worth becoming or being. Only when one has come to perceive that having anything or being anything is a delusion, a deception, a mirage, and that nothing at all is worth getting or worth becoming, has one achieved true wisdom of impermanence, unsatisfactoriness and non-self – Buddhadasa Bhikkhu

Like everything mental, the so-called law of causation contradicts itself. No thing in existence has a particular cause; the entire universe contributes to the existence of even the smallest thing; nothing could be as it is without the universe being what it is. When the source and ground of everything is the only cause of everything, to speak of causality as a universal law is wrong. The universe is not bound by its content, because its potentialities are infinite; besides it is a manifestation, or expression of a principle fundamentally and totally free – Sri Nisargadatta Maharaj
