Is there something in your life that you're holding onto resentment, frustration, or anger towards? Is that something in the past, but your tension on the subject in carrying on into your current reality?
While it may be hard to forget, it's harder NOT to forgive. In fact, if you don't practice forgiveness, you will likely be the one who pays most dearly. By embracing forgiveness, you can also embrace peace, hope, gratitude and joy.
Forgiveness does not mean excusing any harm done to you or even "making up" with the person who inflicted this issue in the first place. What it does entail, however, is a decision to let go of resentment and thoughts of revenge. Ultimately, forgiveness brings a kind of peace that helps you go on with life. With time, it can even lead to feelings of understanding, empathy and compassion for the one who hurt you.
So, how do you "do" forgiveness?
--> You start by bringing about feelings of forgiving and loving in your heart, and then apply them to the circumstance that you feel needs forgiving.
--> Remember times that fill your heart with loving-kindness, and then expand them from your heart to your head and back through the heart down deeply to your belly.
--> This delivers important communication from your heart brain to your head and gut brains - ultimately bring your 3 brains into alignment around deep and total forgiveness.
