Shunyamurti: Symbols can help you practically to live your life at the highest level of sensitivity to the Will of God. Recall, for example, that the Cross on which Yeshua (the ego) is crucified is also the Bodhi Tree, meditating under which Siddhartha Gautama attained enlightenment/Buddhahood. In other words, the cause of your suffering becomes the cause of your liberation.
The Cross is also Holy Rood, the Tree of Life in the Garden of Eden. This equivalence contains the same message: the ego must die for its sins, but it dies into eternal life and bliss.
Questioner: It is not the ego per se. It is the identity in the ego. You say "*your* ego" in the comment; so to whom does the ego belong to?
