This diagram can be viewed in two different ways… either as two boxes or three. Yet the diagram has not changed. The Veda is structured the same way. The apparent contradictions are resolved through deeper understanding and insight. To argue which perspective (two boxes or three) is to misunderstand the structure of the Veda, the structure of existence. Of course, being the underlying dynamic of all existence, the structure of Veda is far more profound than that of this simple diagram. Yet the diagram illustrates the principle. Yantras are geometric representation of the structure of Veda. All yantras are one. In that sense, there is only one yantra, only one God. So it can be said that all the various yantras are contained in the Shri Yantra, just as the simple diagram contains both two boxes and three.
