Ivan Ilyich's death is a particularly spiritual job. That's because we can see Ivan Ilyich was a very privileged person in his life, having access to several material things of value. In addition, iVan was endowed with a successful professional life and a good family life, watered by excesses and a high financial condition. However, when Ivan finds himself in a death situation, he begins to perceive things in a spiritual way.
First of all, it is important to realize that Ivan recognizes that all the material things he has achieved during his life are not able to save him from death, illness, fear, and other feelings. The material does not interfere with the spiritual and in the end, only the spiritual is what matters.
Ivan's wife and son are the only ones who can see him, in addition to his conquests, they can understand his spirit and understand the impact of his death. Ivan also realizes what was the best moment of his life, the moment of his youth, when he reached happiness without artificial things like money and relationships. When Ivan understands these points, his spirit can finally rest in peace and he dies happily.
