Spiritually speaking, all relationships serve one purpose: self-knowledge. Self-knowledge serves one purpose: awakening to the truth of one's self. Awakening to the truth of oneself serves one purpose: dying to oneself. Dying to oneself serves one purpose: rebirth. And rebirth is the purpose and fulfillment of all relationships.
I was very excited to hear this book, but when I started it, the audio was scratchy and the focus (as the title indicates) of reflecting on C.S. Lewis' work, wasn't until close to the end of it. I had expected this presentation to be more focused on spirituality of the LWW, which it isn't.
