"Without the knowledge of the Spirit, all material knowledge is only adding fuel to fire, only giving into the hands of selfish man one more instrument to take what belongs to others, to live upon the life of others, instead of giving up his life for them."

- Swami Vivekananda, "The Real Nature of Man" (The Real and The Apparent Man, June 21, 1896, Royal Institute of Painters, London), Jnana Yoga, Complete Works: Vol 2
