From Theosophy's Sacred Teachings: “The Voice of the Silence,” Fragment I, Part 2 of 2

Watch how they hover over the stormy sea of human life, and how exhausted, bleeding, broken-winged, they drop one after other on the swelling waves. If through the Hall of Wisdom, thou would reach the Vale of Bliss, Disciple, close fast thy senses against the great dire heresy of separateness that weans thee from the rest. Then from the heart that Power shall rise into the sixth, the middle region, the place between thine eyes, when it becomes the breath of the One-Soul, the voice which fills all, thy Master’s voice. Tis only then thou can become a “Walker of the SKY” who treads the winds above the waves, whose step touches not the waters. Before thou set thy foot upon the ladder’s upper rung, the ladder of the mystic sounds, thou hast to hear the voice of thy inner God (the Higher Self) in seven manners.
