Karma by Paul Brunton...

Karma comes into play only if the karmic impression is strong enough to survive. In the case of the sage, because he treats life like a dream, because he sees through it as appearance, all his experiences are on the surface only. His deep inner mind remains untouched by them. Therefore he makes no karma from them, therefore he is able when passing out of the body at death to be finished with the round of birth and death forever.
