Mara was waiting for him with one last temptation. How could the Buddha expect people to understand truth as profound as that which he had discovered? Why not wash his hands of the whole hot world, be done with the body, and slip at once into perpetual nirvana? The argument almost prevailed, but at length the Buddha answered, "There will be some who understand," and Mara was vanquished forever.
