The Mahatmas whom this book depicts are members of our own evolutionary group, not visitors from the celestial spheres. They are supermen only in that they have attained knowledge of the laws of life and mastery over its forces with which we are still struggling. They are not Gods come down to earth, but earthly mortals risen to the status of Christ. They ask from us no reverence, no worship; they demand no allegiance but that which it is expected we shall render to the principles of Truth and Fact, and to the nobility of life. They are our "Elder Brothers," not distant deities; and will even make their presence known to us and grant us the privilege of cooperating with them when we have shown ourselves capable of working unselfishly for mankind.
