I deeply hope persons with a Christian worldview won't bypass this book simply because the author believes in reincarnation. I don't particularly believe in reincarnation but I don't think one needs to do so in order to sense that we are all connected as part of one great wholeness. (I actually think our connectedness means we all have some access to each other's thoughts and memories, etc. which might account for the impression of past lives, but I don't think it's important to know this at this time, I believe we'll all know 'ultimate reality' eventually, are Christians not promised the 'tent of God will be with mankind?')
In the meantime, spiritual teachers such as Gina Lake help point us to the most loving parts of ourselves, she calls it 'essence' and every time she says 'essence' my spirit hears 'that part of you that knows God.' What someone else's inner Self hears in the place of that word I can't predict, but I think you will find it meaningful to find out. What I look for in spiritual teachers is not 'all the answers,' which they can't have anyway, but for a saner approach to all aspects of my life, inner and outer. Those who appreciate writers like Tolle, Ruiz, and especially Byron Katie, will appreciate Gina Lake. I am blessed by this book, and have found myself listening to parts of this recording almost every day.
The narration also is excellent, by the way.
You will want to be able to skip around in the book and look at the illustrations and slow down for the exercises. But the audio is excellent for 'sounding down' the information, and staying inspired to understand your emotional messages, and to keep processing in 'love and trust.'
