When Did The Term “Ego” First Appear?

Question: Science believes that the term “ego” was introduced through Sigmund Freud’s theory of psychoanalysis. But Kabbalah is much older than psychology. When did this term first appear in it?

Answer: In Kabbalah, this term was originally called the desire to receive pleasure. It was introduced by Adam 5,778 years ago.
The desire to receive pleasure is the matter of our world.

Question: And when did the word “Kabbalah” appear?

Answer: I cannot say with full certainty when the word “Kabbalah” began to occur for the first time, but the ancient Greeks translated it as ‘reception’—that is, ‘receiving,” the science of receiving, of disclosure.
