I am pretty sure that I've reviewed Sophy Burnham's book, The Ecstatic Journey: Walking the Mystical Path in Everyday Life, before, but I wanted to touch on some things again. I think that re-reading some things, after having traveled farther along on the path of life, gives one a different perspective. It's a bit like reading a travel guide before and after you've seen the sights.
On my first reading, I felt like the author dwelled too much on her personal journey and emotional experiences, and that felt a little off-putting to me at the time. On my second reading, however, I noticed how she would talk about her mystical insights and then refer to many mystic's writings and experiences from the past. It helped to validate and explain what she lived.
For that reason, I think this is a book worth reading twice, some years apart. It will inform not only your own journey so far, but also the road and sights to come.
