Some students have been asking for recommendations on translations of the yoga sutras.  I would recommend:

 

The Heart of Yoga by TKV Desikachar

An excellent foundation book for this tradition, outlining the principles of yoga – why we practice asana and pranayama, how a yoga practice is constructed, the obstacles we face and how to apply the yoga principles in our everyday life.  It includes a translation of the Yoga Sutra of Patanjali.

 

Liberating Isolation (The Yoga Sutra of Patanjali) by Frans Moors
A long time student of Desikachar, Frans Moors offers a beautiful translation of the sutras with detailed breakdown, word by word, of the Sanskrit. For more in-depth study of the Yoga Sutras.

 

The Yoga Sutra of Patanjali by Chip Hartranft

This is an interpretation, rather than a word-for-word translation, in plain, accessible language with much relevance to 21st century life.  This is a very clear and comprehensive understanding of what lies at the heart of Patanjali’s, sometimes cryptic, Yoga Sutras.
