All growth – no exceptions –  is cancerous until something arises that keeps it in check. Growth has no inherent self control. This is the natur of growth. It is because of the lack in control that it grows.

It is always some other existence keeping it in check. This creates diversity. Everything in the universe obeys this fact. Thus it is the law of diversity.

Our ego-construct as well. Unchecked it creates decease. Higher self is the diversity.
