There are 3 basic levels on which you can talk about for any given subject. Physical, mental, spiritual.
The first, and most obvious, is the one we know the most. This means when you are talking with someone you take everything at “face value”. Funny how our language mimics life in it’s true form huh? At this level there is only one consideration. What you see. If it looks like a duck, walks like a duck, quacks like a duck, it must be a duck!
The mental level gets much more interesting. This is the level where you begin to be more discerning. Things like “Wait. What’s a duck doing in my living room? Am I dreaming?” You start paying attention to details. You try to analyze things, take them apart and see what makes them tick. The vast majority of scientists and hackers reside in this realm.
Then there is the spiritual level. This can be likened to being an observer of events. Where you “step outside of your situation and look at it as if you were completely detached, or rather attached in a much grander scale. Here you can see yourself arguing with someone and take notes in how things interact. Subtle things that become blindingly obvious but get completely missed on the previous levels because they can only deal with their own levels.
The spiritual level is easily identifiable when you are in a deep conversation with someone and they say something that just stops you dead in your tracks. You are whacked in the head with a sudden sense if profound meaning. A Truth is spoken and it’s like a gong going off in your soul.
Another way is to realize that everything on any given level had a mirroring aspect on another level. For example meta-learning. This is where you learn how you learn while you are learning! It is the mental equivalent of being a spiritual observer.
On a physical level such mirroring is different but still the same in essence. Here you would use terms like macro-scale and micro-scale. The planets in our solar system rotate around our sun. Our little galaxy rotates around the Milky Way galactic core. Our atoms circle around a nucleus. These are no small coincidences.
So as a reasonably enlightened person, I would say physical, mental, spiritual. Someone who has a greater affinity for the mental might use point/vector/plane while a person devoted to religion might use father/son/holy ghost. Nicola Tesla liked to use ‘If you want to find the secrets of the universe, think in terms of energy,frequency and vibration.’
Which do you use?
