Reincarnation is change.
Whether in the domain of mind, of natural objects, or of human progress in civilization, the great law governing all is change. This procession of change is evolution, and reincarnation and evolution are the same thing. Now, although the doctrine of reincarnation applies to every atom in the universe, we will only consider it in respect to man himself. If man is the crowning glory, the aim and end of all evolutionary effort, as a conscious reasoning being his evolution must needs involve a changing series of lives. First of all, he should know himself, because once that he knows that, he knows all.
