Existentialization and Externalization of the non-Jews

Torah is the physics of a supernatural reality. A person who eats something G-d says not to is essentially doing damage to his soul, even though the damage may be invisible. You can no more free yourself from the regulations of the Torah and from its consequences than you can from things which affect your physical reality. But if the Torah is the central essence of Creation, then why were only the Jews given those laws? Don't they pertain to everyone? After Adam's sin, different levels of souls were created with different spiritual capabilities. Only one type had the ability to accept and understand the Torah. The purpose of a non-Jew is to keep the seven mitzvos of Noah's sons and to enjoy the fruits of this world. The purpose of a Jew is to work on spiritual matters and create a World to Come.
