When we are able to forgive, we release the resentment/anger/hurt/frustration that our body is holding onto. This frees up energy to focus on healing the body and to help put it in a state of homeostasis.
When my son was seven, he came to me after a melt down and apologized. In his infinite innocent wisdom he asked, “Can we have a Re-Start, Mom?” In that moment, it was so easy to let go of any negativity I may have been feeling. My "Dennis the Menace" has asked for a lot of Re-Starts over the years, and I found that it is the quickest way to change the energy to positive.
Don’t be afraid to ask for a Re-Start when needed. Your body needs it and deserves it.
