The Hidden Power Within YouKanjizai and Rojin

What if something worth millions had been sitting in your home for decades—and you had no idea?

In 2018, a French family discovered a Chinese vase that had been stored in their attic for years.

They did not think much of it. In fact, they reportedly considered it “too pink” and did not particularly like it.

They wrapped it in newspaper, placed it in a shoebox, and took it to Sotheby’s in Paris.

Then came the surprise.

The vase turned out to be an extremely rare piece of 18th-century Chinese porcelain from the reign of the Qianlong Emperor.

Its initial estimate was around €700,000.

It sold for:

€16,182,800

—roughly 14 million U.S. dollars at the exchange rate of the time.

The vase had not suddenly become valuable.

Its value had been there all along.

It had simply gone unrecognized.

And that raises an intriguing question:

Could the same be true of the human mind?

We use our minds every day.

We think, decide, worry, hope, imagine, and dream.

But if someone asked,

“What exactly is the mind?”

how easily could we answer?

The two books we are introducing, Kanjizai and Rojin, explore this mystery—and the hidden spiritual potential within the human mind.

One teaching compares the mind to a treasure storehouse.

A man owns a key for many years without knowing what it opens.

Then one day, he tries it on a storehouse in his backyard.

The door opens.

Inside, he discovers gold, silver, and precious stones.

The treasure had always been there.

The key had always been in his hand.

He simply had not known what it could unlock.

The human mind may be much the same.

We may carry abilities and possibilities within us that remain undiscovered for years.

It can be understood as the power to release spiritual abilities hidden deep within the mind and to expand awareness beyond the ordinary five senses.

But this leads to another important question.

What happens when that power grows?

Think of a sword.

The sharper the sword, the greater its power.

But a powerful sword cannot be carried carelessly.

Without a sheath, it can harm others—and even the person holding it.

That is why a sword needs a sheath.

Spiritual power is much the same.

You may begin to perceive things others cannot.

You may sense another person’s thoughts.

You may receive impressions about the past or the future.

But the stronger such abilities become, the more important it becomes to control them.

Just because you know something does not mean you should say it.

Just because you perceive something does not mean you should display it.

Greater spiritual power requires greater self-control, judgment, character, and common sense.

This is the role of Rojin.

Rojin is the power to possess highly developed spiritual abilities while remaining grounded, balanced, and able to live as a person of sound common sense.

In that sense,

Kanjizai is the sword.
Rojin is the sheath.

Kanjizai releases spiritual power.

Rojin governs it.

The stronger the sword becomes, the stronger the sheath must become as well.

This may be one of the most important ideas for understanding spiritual ability in the modern world.

True spiritual power is not simply about seeing what others cannot see.

It is not about appearing mysterious or extraordinary.

It is about possessing deep spiritual awareness while still being able to work, care for a family, fulfill responsibilities, communicate naturally with others, and live as a grounded human being.

There are times to use the sword.

And there are times to keep it quietly in its sheath.

Having power does not mean displaying it.
Knowing something does not mean saying it.

The greater the spiritual ability, the greater the responsibility to govern it wisely.

Kanjizai — the power to release spiritual ability.
Rojin — the power to master it.

To possess advanced spiritual abilities while still living naturally, responsibly, and sensibly in the real world—

this may be

the highest expression of spiritual power in the modern age.

Just like the vase forgotten in an attic, there may be treasures within the human mind that we have not yet discovered.

But discovering the treasure is only the beginning.

The deeper question is:

What will we do with the power once we find it?

Kanjizai and Rojin offer two sides of the answer—

the sword,

and the sheath.
