Balance

In my opinion, Balance can be in everything, balance is used to mean a point between two opposite forces that is desirable over purely one state or the other, such as a balance between the metaphysical Law and Chaos — law by itself being overly controlling, chaos being overly unmanageable, balance being the point that minimizes the negatives of both.
between structural and emotional as the essence of beauty.

Sometimes in life, just like friends. If most of your friends is aggressive type then its hard too comunicate, but in another way if one of your friends is a kind of people that which is a easy going one. Then the whole relationship changes in to a new phase.

For example:

A and B is having dinner, and suddenly A said somthing that againts B. If both A and B is aggresive, then this dinner will end up like a disaster. They even will fight for it somemore. Faint....

This is another example:

A and B is having dinner, and suddenly A said something that against B, if A is aggressive

and in another hand, B is a patient guy. Then this dinner will become smooth and end without any conflict.

When your making new friends, be sure to find someone like A or B. To neutralise the relationship, and make it better.
