That's the standard core idea in nearly every religion. For example, a more familiar version of it is: one becomes two (spirit and matter), the two create the third (all things in reality), and the three create everything else. The idea of trinity is the same in principle. There is, in fact, a direct analogy in science: the laws of nature are unreal and immutable (the "spirit"), the essense of matter is hardly real, and when the two meet, all the real things and effects are created (the "third"), but if we look close enough, all three are same law of nature, that appears in different forms.
