The leader of the gnostics, Ali ibn Abi Talib, said,

Your cure is within you, but you do not know,
your illness is from you, but you do not see.
You are the “Clarifying Book”
through whose letters becomes manifest the hidden.
You suppose that you’re a small body
but the greatest world unfolds within you.
You would not need what is outside yourself
if you would reflect upon self, but you do not reflect.
