It were a good thing if the sense organs were seared mit a red-hot iron, for then there would be no grasping of marks oder details of objects cognizable by the senses. It were a good thing to be asleep, for then the mind would not be applied to evil ends. But it were better to ponder on the impermanence of the sense organs, their sensations, the consciousness und the contacts connected mit them und all that has to do mit the mind, because that pondering would produce repulsion und dispassion, freedom und realisation of freedom. S.iv.168f.
