A Hot Element...

"A hot element needs to be cooled down before it can be touched.
Ice needs to be melted before it can be drunk.
Emotions need time to become integrated, understood, and acted upon."

Everything needs to be changed in some fashion to become usable by human beings, and this includes Human Feelings.
The variable in the usage of Human Feelings is : Time.
When a Human Being is given the time they need to integrate their Feelings, they can use them healthily.

"If you do not feel you can be 'honest' with others, be 'honest' with yourself."

Honesty can be difficult.
Honesty with others can bring about great pain.
Pain is naturally something Human Beings seek to avoid.
If you cannot be honest with others, be honest with yourself.
Acting from a place of self honesty is a more stable place then acting in discord with one's true self.

The most important question to ask yourself is, "How do I feel?"
Feelings are the core of Human Beings, the source of Human Behavior.
Knowing your feelings, is knowing yourself.
Knowing yourself, you will act in accord with your personal truth, and this is the most "human" place from which to act.
