Who is the Enigma?

"When we think with all our mind, with all our heart, with all our soul; when we become aware of the fact that the self cannot stand on its own, we realise that the most subtle explanations are splendid enigmas, that God is more plausible than our own selves, that it is not God who is an enigma but we."

- Rabbi Abraham Joshua Heschel
from Man is Not Alone, 1951
