What I've read is, your personality is made up of different qualities that correspond to different elements, and most usually have one that is dominant. The aim is to try and make sure you have a balance of all elemental qualities, including akasha or spirit, the fifth.
Depending on your path, it will mean different things, but you use the knowledge to develop yourself as a full, whole, rounded person grounded in all the corners of reality, so that your will is more focused and therefore you can work stronger magic.
Plus your question marks are really annoying, you look way frantic. I know you're probably just letting us know your emotion, but it's good to calm down, slow down and ground yourself a bit, also for focus and strength.
