Removing Confusion

Yoga corrects misperception to free us from suffering.

That's the basic message of most ancient texts, but there are many different teachings and some contradict each other. How do they all fit together? What explains why they change?

The Truth of Yoga is a comprehensive guide to how yoga evolved. The book highlights themes that have shaped its development, while the courses on this site bring those subjects to life.

Their format is:

  • Engaging, interactive and fun
  • Designed for practitioners
  • Grounded in evidence

If you've ever felt puzzled by yoga philosophy – or how traditional ideas relate to modern priorities – you're in the right place for some practical insights and straightforward clarity!

Guy Raz

"If you are [a] student of yoga or simply interested in its historical and philosophical underpinnings, you will walk away from this book wiser."


Monica Milano

"If you’re both fascinated and overwhelmed by yoga philosophy, this is the book for you... It’s the book I wish I was assigned for my 200 hour training."


Matthew Hahn

"I am always asked by students what non-academic books they could read... I had high hopes for [The Truth of Yoga] and it did not disappoint."
