We are all children of God. God is light, and we are also light, being of the same essence as that of God. But our light is enveloped by different coverings – physical, astral, causal and supercausal. Initiation means to raise up our soul and shake off the coverings: first, the one of the physical body, which is the iron curtain, I would say: to raise the soul above body-consciousness – physical consciousness – and open the inner eye to have an experience of light, and also to open the inner ear to hear the voice of God, or the music of the spheres.
