Elemental Interconnections Options

An aspect of the Enochian paradigm that I appreciate is how the elements are interconnected with each other. For example: water of earth; air of fire; earth of air; etc... To me, such interconnection enriches Enochian's elemental model.

However, I'm not clear about why a kind of elemental interconnection is included. Specifically - interconnections of the variety: earth of earth; water of water; air of air; etc...

I ask because while I comprehend that the interconnections for each element provide further insight regarding each element - yet, at this point, I don't comprehend how earth of earth is not simply earth, how water of water is not simply water, how air of air is not simply air, etc...

Explanations for why interconnections of that variety are included would be welcome.

Suh-Wing Batta, batta, batta! LOL! I frequently miss the point...but that's half the fun!
The elements make up everything but not in their pure form. As we ascend the spiritual ladder we come closer to experiencing the elements in their pure form. They are, in this form, a constant, an archetype. As we descend the ladder the interaction between the elements gets more and more mixed or variable. Quixotic isn't it? A spiritual conundrum (that's short for 'I don't know why...') The addition of the 5th element remains all pervasive and is denoted within the Enochian system as having elemental variables to link this element to the others. Some find it more of a convenience...depending on your point of view!
