The Buddhist aspects of these issues have been relatively submerged, although I have focussed on the crucial question of the relation between ‘knowledge and vision of things as they are’, on the one hand, and the obstacles to that possibility in the form of the ‘three poisons’, on the other. I have referred to the significance of energy and its diversion into various forms of distraction, and discussed the conditions for the possibility of listening and hearing, as well as das Offene and ‘freedom’. Perhaps not unexpectedly, some of these themes emerge in the work of Martin Heidegger, in particular in his writing about what he calls ‘the essence of technology’ (1977), marred though it is by his anti-Semitic diary entries.
