In order to figure out what it feels like, focus your breathing in your heart: see your breath go in and out through your heart as you think of someone or something you love. Know what that feels like because it actually changes your physiology and brings your heart and your brain into coherence and balance. During the process be sure to forgive yourself and remember to appreciate all of your accomplishments.
When you are faced with a challenge, you can remember and apply that feeling as you intentionally look for the good and the lessons of that challenge. This brings about a lightening and an expansion that helps you deal with the curve balls that inevitably come your way. The key is to be flexible and resilient and use all the tools in your toolbox to maintain balance in your life.
