If you are conscious, you don't fwed the sharks inside you. Our dual nature demands a constant struggle between what is right and what is wrong. There will always be sharks and dolphins inside us. Duality exists in the entire universe. And by the way, although we like to use sharks as a metaphor for something dark or evil, sharks in the ocean are not always predatory.
Your observations are true for a person with "normal balance." The universe also seeks balance. And there is a place for sharks. But why constantly feed the sharks while excluding the dolphins? Is that not creating an imbalance?
