Question: Even the Talmud says that one judges according to his own flaws, that everyone judges according to his level of corruption, which means that even back then people understood that by changing their properties, they would be able to see the world.
Can we say that the connection with others was given to a person only so that he can check his attitude toward them since a person sees what is negative in others, and what is in him he always sees as positive? How can we use this principle in order to advance?
Answer: The external world exists only in a person’s perception, but he cannot say whether it exists externally to him.
Does the world continue to exist for a person who lives today but is gone tomorrow, or not? A person cannot determine or prove that. No one can determine or prove that, including Newton, because with regard to each of us, the whole world is an absolute, subjective illusion.
One may say that we see how a person dies and the world continues to exist, but with regard to the person who died, we cannot determine anything because we don’t share his feeling.
Thus a person was created like that in order to alter his attitude to others, which for him is the indication of exiting himself and of feeling the upper world outside himself. The world outside a person is the upper world.
