Light on the Yoga Sutras of Patanjali (英語) ペーパーバック – 2003/1/1
"Patanjali's Yoga Sutras is the bible of yoga..."
"BKS Iyengar is renowned throughout the world... his inspired commentary on the ageless treatise by the ancient sage speaks to the soul of every dedicated yogi."
Phil Catalfo, Yoga Journal
I am a little unimpressed with the packaging though on Amazon's part. I was expecting the typical cardboard book box that is easily recycled and instead got a plastic bubble wrap package which can not be. I know people will say I can save it to reuse, but haven't managed that in the past as I have a drawer full of them already. Also the bubble wrap didn't protect it anyway, as there is damage to the spine due to impact of hitting the floor after being pushed through letter box.
Moan over. Buy the book if you're interested in deepening your understanding of the philosophy and teachings behind yoga. There is so much more to it than being flexible and making "shapes".
