Am I supposed to be? Am I supposed to be worried about having been born?
Intelligence has to do with the soul, not simply with the brain.
No it hasn't. There is no soul - that's an invention of religion.
Take electricity, for example. Electricity moves between gross elements and through a gross wire. But the electricity itself -- it is not those elements, not that wire. It is subtle.
Actually, no!. The electricity is the result of the electrons of the metal of the wire being passed down the wire, an atom at a time all around the circuit. Thus the electricity is in fact part of the wires not something separate or mysterious.
