Demonic and spirit energy are essentially embodiments of the yin-yang philosophy. To lay it out in simple terms:

Demonic energy = female energy = yin.

Spirit energy = male energy = yang.

In this regard, Cross' world is following certain Eastern philosophy, which places a heavy emphasis on balance. Male and female balance each other, light and darkness, etc. The forces do not so much compete as they compliment. In each of those sets, the one cannot exist without the other, and the whole they create is greater than the sum of its parts.
