Imagine a very poor man living in a decrepit little shanty, the only thing he owns in the world. What he does not know is that just beneath his shanty, but hidden in the dirt, is an inexhaustible vein of gold. As long as he remains ignorant of his hidden wealth, this pauper remains in poverty; but when he attends more closely to his own dwelling, he is bound to discover his own fathomless wealth. Similarly, all we need to do is unveil our own nature, and we will find an inexhaustible source of wisdom, compassion, and power. It is nothing we need to acquire, from anywhere or anything. It has always been there.
Seen in this light, the Buddha-nature requires no additions. One does not have to memorize sutras, recite prayers, or accumulate virtues to create it. All one needs to do is unveil it.
