"The Vimalakirti Sutra states that, when one seeks the Buddhas' emancipation in the minds of ordinary beings, one finds that ordinary beings are the entities of enlightenment, and that the sufferings of birth and death are nirvana. It also states that, if the minds of living beings are impure, their land is also impure, but if their minds are pure, so is their land. There are not two lands, pure or impure in themselves. The difference lies solely in the good or evil of our minds."
