“More valuable than treasures in a storehouse are the treasures
of the body, and the treasures of the heart are the most valuable
of all. From the time you read this letter on, strive to
accumulate the treasures of the heart!”
Nichiren indicates the order of priority of the three kinds of treasure and sets forth a clear standard of value.
Kingo faced the possibility of losing his estate, which, of course, represented an extremely important source of income for him and his family. But the Daishonin insists that far more valuable than the treasures of the storehouse and the body are the treasures of the heart. The accumulation of these inner treasures, he says, is the basis for all victory.
The fact that Kingo had been challenging his situation based on faith in the Mystic Law corresponds to placing the highest value on the treasures of the heart. As a result, he had been victorious so far. That is probably why Nichiren clarifies this point as a universal and unchanging guideline for victory in all areas
And actually, when we base ourselves on the treasures of the heart, the true value and worth of treasures of the storehouse and the body also become apparent in our lives. In short, we need to make accumulating the treasures of the heart our fundamental purpose in life. If we lose sight of this elemental objective, seeking merely to accumulate treasures of the
storehouse and the body, it will give rise only to attachment. Fear of losing such material or physical treasures can then become a cause of suffering. Therefore, what is important above all, what is the correct sense of purpose in life, is to accumulate treasures of the heart.
