Kabbalah sur La Genèse 2:17

Know that when the first man sinned by eating the fruit of the tree of the knowledge of good and evil, both his body and soul took on a composition of good and evil. This is the matter of, “the dross of the serpent”, that was instilled in Eve and Adam. This dross brought about illness, disease and death, both spiritually and physically. This is the secret of the verse⁷Genesis 2:17, “For on the day that you eat from it, you shall surely die” – meaning the death of the soul, as well as the death of the body⁸The literal translation of the verse is, “Die, you shall die”, i.e. physical and spiritual death..
