Humanity. Occultly and Kabbalistically, the whole of mankind is symbolised, by Manu in India; by Vajrasattva or Dorjesempa, the head of the Seven Dhyani, in Northern Buddhism; and by Adam Kadmon in the Kabbala. All these represent the totality of mankind whose beginning is in this androgynic protoplast, and whose end is in the Absolute, beyond all these symbols and myths of human origin. Humanity is a great Brotherhood by virtue of the sameness of the material from which it is formed physically and morally. Unless, however, it becomes a Brotherhood also intellectually, it is no better than a superior genus of animals.
