“Anthroposophy is a path of knowledge, to guide the Spiritual in the human being to the Spiritual in the universe. It arises in man as a need of the heart, of the life of feeling; and it can be be justified only inasmuch as it can satisfy this inner need. He alone can acknowledge anthroposophy, who finds in it what he himself in his own inner life feels impelled to seek. Hence only they can be anthroposophists who feel certain questions on the nature of man and the universe as an elemental need of life, just as one feels hunger and thirst.”[Steiner, Rudolf. Anthroposophical Leading Thoughts, London: Rudolf Steiner Press, 1973]
A person seeking inner development must first of all make the attempt to give up certain formerly held inclinations. Then, new inclinations must be acquired by constantly holding the thought of such inclinations, virtues or characteristics in one’s mind. They must be so incorporated into one’s being that a person becomes enabled to alter his soul by his own will-power. This must be tried as objectively as a chemical might be tested in an experiment. A person who has never endeavored to change his soul, who has never made the initial decision to develop the qualities of endurance, steadfastness and calm logical thinking, or a person who has such decisions but has given up because he did not succeed in a week, a month, a year or a decade, will never conclude anything inwardly about these truths.
