For nearly 2000 years the supreme oneness has been hidden from the world. The religious leaders, not the prophets, wanted to keep people in darkness. The archons even now are terrified of even one person finding the light of supreme oneness. The lamp is shining. Nous is the lamp. To know what is ever lasting and what is not is the Gnosis.
The lamp within guides us , leads us to ever more within. The world follows what someone else has written and never follows the truth within themselves. Thus the darkness prevails. The religions speak of the lamp symbolically but it largely gets ignored like a hidden secret.
