I've been reading this book.
THE SACRED SITES BIBLE - a definitive guide to all places spiritual around the world. (by Anthony Taylor). 10 out of 10.
I am a little bit into Buddhism, religion and spirituality. I learned so much from this book, from holy rocks to caves, to churches, temples....and their background/meaning. I recommend this book to anyone who's into religion/body/mind and spirits. My favorite sections are the temples in Asia, churches in England/Ireland and the native people/sacred rocks in Australia.
