The powers and forces which draw man upwards again to the spiritual world fall into two categories: those which draw him upwards on the path of Wisdom, and those which draw him upwards on the path of Morality. The forces to which intellectual progress is mainly due all proceed from the impulse given by a great Individuality of the fourth post-Atlantean epoch who is known to you all, namely Gautama Buddha. It is a remarkable discovery of spiritual investigation that the most penetrating, most significant, thoughts conceived in our present epoch have proceeded from Gautama Buddha.
The second impulse which, in addition to that of Buddha, continues to work in the evolution of humanity is the Christ Impulse and is connected with the future ascent of humanity to Morality. Although Buddha’s teaching is in a particular sense moral teaching, the Christ Impulse is not teaching but actual power which works as such and to an increasing degree imbues mankind with moral strength.
