Context: "Thou art come back to me, Thou art come back to me! O Thou, whom I had lost!... Why didst Thou abandon me?"
"To fulfil My task, that thou didst abandon."
"What task?"
"My fight."
"What need hast Thou to fight? Art Thou not master of all?"
"I am not the master."
"Art Thou not All that Is?"
"I am not all that is. I am Life fighting Nothingness. I am not Nothingness, I am the Fire which burns in the Night. I am not the Night. I am the eternal Light; I am not an eternal destiny soaring above the fight. I am free Will which struggles eternally. Struggle and burn with Me."
