The Theosophical Movement is the brotherhood of humanity established to make clear every dogmatic religion founded on dead-letter interpretation, and to point out the existence and the belief in One Impersonal God; man is able to rely upon his own powers and be his only saviour; he can realize the infinitude of the occult psychological powers hidden within himself and develop these powers; to give man the assurance of his divine spirit's immortality and of his soul's survival.
Ethics are the fundamental basis of the human behaviour as this is the only way to establish goodness, justice, altruism and compassion, necessary prerequisites for a universal Brotherhood. The noble ideal of universal brotherhood can only be realized if we can become better human beings. Brotherhood is possible for one who is aware that he is a part of the Oneness.
Madame Blavatsky in a letter to W Q Judge on 29-11-1878
