The left and right wing belong to the same bird and in the middle is the brain. The left and right wing cannot fly by themselves and they do not have control of the direction they fly.
It is in the middle that the power is held for the left and right wing cannot talk to each other without the body of the bird in the middle.
The world is filled with opposite views. Yet the true power is found when one does not get lost on one side, but uses the power of each side to direct life.
The left wing is powerful, but it is not balanced.
The right wing is powerful, but it is not balanced.
Use you left and right wing wisely picking when to use one or the other. If you only build up one side of a building it is not a stable structure.
The same with life. Balance the aspects of the self and other. Do not be altruistic or hedonistic. Look not for rules but tools. Find the middle way where the right side of your body can work with the left because it is hard to walk down a path with only one leg, it is impossible to fly with only one wing.
