What does this mean? Dull nothingness (akincanna) is a thought form with a non-descript content. In other words, a thought is generated which is defined by the usual boundaries and parameters that constitute the average structured ‘thought’ form – but the meditator misunderstands this ‘non-descript’ content and mistakenly grasps it as being the empty mind ground. The trap here is that a manifest ‘thought’ (and stream of thought) is masquerading as the psychic fabric from which all structured thought arises – and which pre-exists all thought. This state is mistaken as complete and perfect enlightenment and those trapped within it start misleading others down the wrong path.
