This is one of the most popular classic translations of Steiner's foundational guide to the spiritual path. Knowledge of the Higher Worlds and Its Attainment is a manual for attaining suprasensory knowledge of the invisible and opens new perspectives on one's essential purpose in life. In 1904, Rudolf Steiner first made this account of the Western esoteric path of initiation public. With great precision, he carefully leads us from the cultivation of the fundamental soul attitudes of reverence and inner tranquility to inner development through the stages of preparation, illumination, and initiation. Practical exercises in inner and outer observation and moral development are given. By patiently and persistently following these, new organs of soul and spirit begin to form that reveal the contours of the higher worlds hitherto concealed from us. "The methods by which a student is prepared for the reception of higher knowledge are minutely prescribed. The direction he is to take is traced with unfading, everlasting letters in the worlds of the spirit where the initiates guard the higher secrets. In ancient times, anterior to our history, the temples of the spirit were also outwardly visible; today, because our life has become so unspiritual, they are not to be found in the world visible to external sight; yet they are present spiritually everywhere, and all who seek may find them."
