The Buddha's fifth dream evokes both the extraordinary and the ordinary nature of his achievement. He walks on a mountain of dirt and is not fouled by it. Note that the dirt is not transformed into gold or anything. It stays dirty. But the Buddha, astride his pile of dirt, is untouched by it. This is another version of the third dream, in which that which was seen as a barrier to awakening is now known as the foundation upon which it rests. Enlightenment does not mean getting rid of anything; it means changing one's frame of reference so that all things become enlightening.
