" And suddenly it became clear to him that what had been oppressing him and would not leave him suddenly was vanishing all at once—from two sides, ten sides, all sides. … ‘And the pain?’ he asked himself. ‘Where has it gone? Now, then, pain, where are you?’
He waited for it attentively.
‘Ah, there it is. Well, what of it? Let it be.’
‘And death? Where is it?’
He searched for his accustomed fear of death and could not find it. Where was death? What death? There was no fear because there was no death.
Instead of death there was light.
‘So that’s it!’ he exclaimed. ‘What bliss!’
All this happened in a single moment, but the significance of that moment was lasting. "
