John Mayer - Heart of Life Lyrics Meaning

My ex-husband, who I will always love, would tell me to listen to this song because he wanted it played at his memorial service - I did...and we did. I think it means that no matter how bad it is, no matter how bad it hurts, no matter how hard it is to hear that someone is saying good-bye, no matter if the pain is so freakin' unbearable you don't think you can lift your head from the pillow and you want to die yourself...that in the end, even with all the curve balls life throws at you, life is good. It's beautiful and comforting.
