While Sri Aurobindo was in jail, Swami Vivekananda appeared before Him, gave Him the Gita and showed Him the Supermind. He did not tell Him how to reach the Supermind. It took Sri Aurobindo ten years to discover it. Like Buddha and Vivekananda, Sri Aurobindo refused to accept moksha for himself while all the other souls languished in the darkness of the earth. One should reach Supermind and bring it down so that it would transform the earth - abolish Ignorance, suffering, evil and death. Sri Aurobindo said that if twelve or a hundred yogis reached the Supermind, it would descend on earth.
