I've been attending a weekly yoga class for about a year now and really enjoy it in terms of physical improvement and relaxation, but feel I've hardly scratched the surface in terms of a deeper understanding of what I'm doing in class and why.
I'd like to ask my other half to get me a really good 'introduction to yoga' type book for Christmas as a jumping off point to learn more about the history, philosophy etc as well as the physical side, and how to go about planning a decent home practice. Could anyone recommend a book (or a couple of books) that would cover this? Thanks!
