I think that depends on you - those are great additions for me, totally. Also a fan of Bruce Lipton (his stuff is all over YouTube - I prefer to listen that way) & Deepak Chopra.
It's less "traditional" but fits perfectly into my mindset, spirituality and recovery.
ETA - I found The Shack to be monumental for me in terms of understanding forgiveness. I loved the storytelling of it, which also made it easy for DD to digest.
