Question: It is written, “For the inclination of a man’s heart is evil from his youth.” Why from youth?
Answer: Egoism begins to develop in a person from youth. We see this in modern children. Previously, children were friends, played together, and connected to each other. And now this does not happen.
Today, children are constantly competing, suppressing each other. It comes from their nature, they are born this way. Up to the age of two or three years old, they are still absorbed in themselves, and when they begin to notice the world around them, and first of all, their own kind, they have a desire to take everything that others have.
The development of egoism is a law of nature. As a consequence, there is separation between people.
