Pure mind, impure mind and ordinary being ,Buddha

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. It is the same with a Buddha and an ordinary being. While deluded, one is called an ordinary being, but when enlightened, one is called a Buddha. This is similar to a tarnished mirror that will shine like a jewel when polished. 7/3
