There's nothing in this realm that is inherently good or bad.

You're the one who decides to give it meaning.

There is nothing to feel guilty about. Every choice is valid and all have consequences. If you don't like the way certain choices pan out, make better choices. Look at why you took a certain action, what was it that you believed to be true that turned out to be false?

Wisdom comes from reflection of the choices you & others have made. The golden rule is wisdom captured in a simple saying. You can write a book on the golden rule but the more words/symbols used, the further from truth we drift.

A lack of fear or guilt means you have nothing to constrain your action. You're free to make choices & experience their effects. This is why many churches & govts try to fill people with fear & guilt. They become far easier to constrain & control.

There are laws in this realm that go beyond those created by any man. What you put out, is what you get back. This is why the golden rule is an excellent rule to adopt.
