What are emotions?

An emotion is energy in motion. It's an electrical charge.

All energy is completely neutral. There are no positive or negative emotions.

Perceiving an emotion as positive or negative is nothing but the meaning you assign to a feeling. Once you stop assigning meaning to your mental or physical experiences and see them as what they are - an energy rising, an energy in motion - you are not only free. You can also use this energy and transform it to create more powerfully. Energy cannot be created or destroyed. If a wave of energy builds up in your cells, you have the power to use it for what you want to create. Each energy wave is a creative gif.

A practical example: In treating anxiety around public speaking, speaking coaches will often have their coachee rephrase "I am afraid" into "I am excited." It's the same physical and mental energy in motion. It's just a different meaning we attach to these physical symptoms and with practice over time, we can turn something we choose to label as "negative" into something we choose to label as "positive" and use the energy in motion for us to propel us forward - and no longer against us.
