I make a few huffing-and-puffing contributions to this week's Something Understood, discussing yoga and demonstrating pranayama breathing. The programme, entitled "Breath, You Invisible Poem", was broadcast this morning on Radio 4. It features readings from Rilke, Haruki Murakami and Maurice Merleau-Ponty, among others. There's also music from Maria Callas and Nick Cave, plus a haka by New Zealand's All Blacks - and Sanskrit read by me.
