THINK ON IT DAY AND NIGHT. FILL THE MIND [ WITH IT ] DAY AND NIGHT - I AM THE LORD OF THE UNIVERSE

[This truth] is first to be heard. Hear it first. Think on it day and night. Fill the mind [with it] day and night: "I am It. I am the Lord of the universe. Never was there any delusion.... " Meditate upon it with all the strength of the mind till you actually see these walls, houses, everything, melt away — [until] body, everything, vanishes. "I will stand alone. I am the One." Struggle on!

NO FEAR! SPEAK NO MORE OF GOD AND SUPERSTITION OF THE WORLD. I AM THE INFINITE

[It is] difficult. Struggle on! Down with all superstitions! Neither teachers nor scriptures nor gods [exist]. Down with temples, with priests, with gods, with incarnations, with God himself! I am all the God that ever existed! There, stand up philosophers! No fear! Speak no more of God and [the] superstition of the world. Truth alone triumphs, and this is true. I am the Infinite.
