Just as oil is present in a mustard seed, all of us, all sentient beings, have Buddha Nature. Though it is present, we do not recognize it, because our minds are obscured by delusions. When, as a result of the view, meditation, and action, we come to recognize these delusions, we can get rid of them in a moment. In one day, sentient beings can be transformed into Buddhas.
