So basically, the theory is that we evolve according to our environments. If our environment expanded beyond the scope of the earth, then so would our brains and minds. If it became smaller, then so would we.

The planet's axis shifts and in several hundred thousand years (a small time frame in the course of eternity) the poles will have reverse and our physical North pole will be where the south once lies. Does this change which direction is North and Which is south? It's interesting to ponder.

The statement I made in the words of a Taoist aren't a quote but rather, an attempt at explaining a condition through another view. I find it helpful in understanding cultures to try and Role Play as one in this sense. Using what the culture would deem logic or philosophy as best as possible.

Is your quote from the Tao Te Ching? I have definitely read it somewhere before, and I'm glad you brought it up where you did, It makes my point well and brings yet another similar quote (paraphrased):

"When the beginner is attacked, he thinks only of protecting himself from any strike. When the practitioner is attacked, he thinks of using the technique and knowledge acquired through training. When the master is attacked, he only thinks of protecting himself from any strike."

Your photograph of the window question is in that same line of thought. North, south, east and west are man made directions, created within the framework of our own world. But the entire planet is rotating on an axis and around the Sun within our solar system, while our solar system is rotating around another point within our galaxy, and our galaxy is rotating around another point somewhere else in the universe while the universe itself is rotating. Are they all on the same horizontal plane? Not even close.

So tell me, which way is north, south, east or west? There is none. Or conversely, all directions equates to no directions while each direction equates to every direction. This is to say that directions are only relative within a given limit of space and time. We’ve become attached to the concepts of directions because we live in this human world.

“The Tao exists and the Tao doesn’t exist.” I’d say that sounds fairly Daoist, although I’ve never heard that exact statement. But it does remind me of another Daoist quote:

“Before I received the Dao, a cloud was a cloud. When I received the Dao, a cloud was no longer a cloud. When I became one with Dao, a cloud was a cloud again.”

It also makes me think of the relationship between hard and soft martial arts. Zee sounds more aggressive to you, and the Dragon Ball Z series is known for its hard hitting action. This is like a hard external martial art. But Zed sounds softer and you relate to the series because of its aspects of character development. This is like a soft internal martial art.

It seems that Dragon Ball has both the soft and the hard. The Yin and the Yang. Perhaps that is why so many can relate to it.
