I'm looking forward to presenting a session on the history of yoga at this year’s World Yoga Festival. Held upriver from London at the end of July, it’s billed as: "Four rejuvenating days incorporating yoga asana from many different lineages, pranayama, meditation, non-duality, Ayurveda, chanting, kirtan, wisdom talks and music concerts in a series of large, decorated and carpeted marquees set in a country park beside the river Thames.” The vibe is "somewhere between retreat and festival," the organisers add. You can find out more and book tickets here.
