The soul of the great Yogi-King has awakened, and he mastered the tides of Nature and met naked Hell with his bare spirit. Now he can see the hidden heart of Night. He is in deep levels of the Inconscience where a Nature denies the eternal Truth and hopes to abolish God. He sees an immense negation of spiritual things and great evil beings who have no inner spirit. It is a place where Heaven’s face becomes a mask and snare of Hell. A monstrous birth prepared its cosmic form in Nature’s titan embryo, Ignorance. A seeking mind replaced the seeing Soul. Sri Aurobindo describes how the dire antagonist Energy, hostile to the true Mother-force, sees the One grow in the heart of time and sees the Immortal shine through the human mould. She does her best to slay the soul. This is the tragedy of the inner death when forfeited is the divine element and only a mind and body live to die.
