As human life extends as an indivisible whole through all three states and is never limited to any one of them alone, it is unscientific and unphilosophic arbitrarily to select the waking condition and ignore the facts of the other two. All the data obtainable ought to be secured, and then integrated into a synthetic system by apprehending them simultaneously in their entirety. The synthesis of all life's states can alone produce sufficient data upon which to grasp the true nature of the world. Only a superior mind, free from vulgar prejudice against sleep and dream, will realize the immense importance of such co-ordination.
