Yet, this analysis is only partial. This much has been known even to modern physical science. Beyond that, the research of physical science cannot reach. But the inquiry does not stop in consequence. We have not yet found that one, by knowing which everything else will be known. We have resolved the whole universe into two components, into what are called matter and energy, or what the ancient philosophers of India called Akasha and Prana. The next step is to resolve this Akasha and the Prana into their origin. Both can be resolved into the still higher entity which is called mind. It is out of mind, the Mahat, the universally existing thought-power, that these two have been produced. Thought is a still finer manifestation of being than either Akasha or Prana. It is thought that splits itself into these two. The universal thought existed in the beginning, and that manifested, changed, evolved itself into these two Akasha and Prana: and by the combination of these two the whole universe has been produced.
