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.
NichirenNever let life's hardships disturb you. No one can avoid problems, not even saints or sages.
NichirenBy an increase in anger, warfare arises. By an increase of greed, famine arises. By an increase of stupidity, pestilence arises. Because these three calamities occur, the people's earthly desires grow all the more intense, and their false views thrive and multiply.
