My yoga teacher once told me that if I practised the Five Tibetans every day then that was yoga-in-a-nutshell, and if I didn't add any more asanas then that would be enough. I think she was probably simplifying it for me a little bit, and sometimes doing these five exercises you feel as if you need to add a few more moves, but actually I think these five make the perfect core to your yoga programme. I've now bought this book for all my yoga-loving friends, and even those who want to get into yoga. Highly recommended.
