Without Karma and Reincarnation evolution is but a fragment; a process whose beginnings are unknown, and whose outcome cannot be discerned; a glimpse of what might be; a hope of what should be. But in the light of Karma and Reincarnation evolution becomes the logic of what must be. The links in the chain of being are all filled in, and the circles of reason and of life are complete.

Karma gives the eternal law of action, and Reincarnation furnishes the boundless field for its display. Thousands of persons can understand these two principles, apply them as a basis of conduct, and weave them into the fabric of their lives, who may not be able to grasp the complete synthesis of that endless evolution of which these doctrines form so important a part.

In thus affording even the superficial thinker and the weak or illogical reasoner a perfect basis for ethics and an unerring guide in life, Theosophy is building toward the future realization of the Universal Brotherhood and the higher evolution of man. --W.Q.
