Very intense reading has brought about a complete transformation in the lawyer. From a man desiring to be a millionaire, he has become a person who despises the idea of accumulating material wealth or the so-called riches of the world.

The greatest wisdom that he has acquired in the fifteen-year long period of his solitary captivity is that he has understood the transient nature of human life and, thus, the futility to heap up wealth or gratify oneself with sensuous delight.

The mortal nature of human body and the pointlessness to invest one’s most precious asset time to attain objects of pleasure and comfort for this mortal body lies at the crux of the teachings of any major religion in the world.

This is what the lawyer has realized. He says,

"I despise wisdom and the blessings of this world. It is all worthless, fleeting, illusory, and deceptive, like a mirage.  You may be proud, wise, and fine, but death will wipe you off the face of the earth..."

One would not indulge in sensual satisfaction if one understands the mortal nature one’s existence. They are considered to be enlightened beings who have this realization. The lawyer by reading philosophies, religions, history, literature and books in at least six languages has acquired this rare understanding of the true nature of life and human existence.

What he does towards the end of the story is not something possible to be done by any ordinary man. It’s rather a rare feat that speaks at length about the lawyer’s acquisition of the highest level of spiritual knowledge. It tells us that the lawyer has not just read but experienced and embraced the great esoteric wisdom of human existence and this world.
