Mankind's soul/spirit is not only fragile and easily corrupted left unprotected and unguarded.
So Light beings devised a plan to protect Humankind by assigning guardians to keep watch over them.
You may watch or refer to The Golden Compass film to have an idea or two on how the Guardian System is like.
Have you ever wondered why you could hear voices, tips, advices, or unpleasant ideas in your head?
The pleasant ones are usually from your guardian and unpleasant ones are dark being wanting to feed off your negative energy (sometimes, it is your darker self, we'll get into more info on that, in another post).
One person has at least one Guardian to guard them. As we mature and evolve ourselves from overcoming our personal fear and obstacles. Our guardian, grows stronger as well. So, one is enough.
However, if we are depressed: emotionally (always envious, sad, angry, self-pitiful, etc.) and spiritually (not doing the things we love that bring us joy). It will inflict pain on one's Guardian.
But if the pain is too much to bear for the Guardian, they will die/perish. Which leaves us in a more depressed or miserable state, a void. What keeps us in-balance and in-check is due to our connection to our Guardian.
Ever noticed how someone who is joyful, cheerful and happy, emits our so much energy that you feel refreshed or given energy?
For someone who is in a miserable/unhappy state. A void is an energy absorbent, even if they absorb positive energy, it will turned into negative energy. When you hang out near negative people, you will feel tired from being just nearby them.
However, if the person can overcome this void, a new Guardian will be assigned or born from the person's achievement from overcoming their personal fears and/or obstacles.
The type of Guardian one has, can show us what kind of person we are, personality-wise.
We'll get more info on what kind/type of Spirit Guardian represents in a person's characteristic, in another post.
Additional info will be updated.
