SRI RAMAKRISHNA (to Mahima): "Go forward. Push on. You will discover the forest of sandalwood. Go farther and you will find the silver-mine. Go farther still and you will see the gold-mine. Do not stop there. Go forward, and you will reach the mines of rubies and diamonds. Therefore I say, go forward."
MAHIMA: "But, sir, something holds us back. We can't move."
