You may ask, "If all comes from the One, the Same, why is one thing truth and one falsehood?" Truth is that which lives, which remains, which stands upright. False is that which falls, which is dead. While we are alive we stand upright; when we are dead we have fallen down. What is dead? This false self, this mortal self. This is fana, destruction. The cross shows that in fana -- in the ending of the mortal, of that which is changing, dying every moment, which lives upon mortal food in mortal surroundings -- is the immortal life. What is not fana the Sufi calls baqi. This I can explain as ba yaki, oneness. In the death of the mortal there is life, immortality, the one immortal life.
