Flint has the potential to produce fire, and gems have intrinsic value. We ordinary people can see neither our own eyelashes, which are so close, nor the heavens in the distance. Likewise, we do not see that the Buddha exists in our own hearts.
NichirenThat which you give to another will become your own sustenance; if you light a lamp for another, your own way will be lit.
NichirenThe 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.
