It’s a hot (are there any other?) day in Rishikesh, the ‘yoga capital of the world’, where I’m attending a yoga retreat. It’s been a few days already and I’ve settled into a little routine. The 5 am meditation sessions combined with blistering heat mean that the time between lunch and the afternoon yoga practice are devoted to napping. But when my roommate Renee asks ‘Do you want to go see the Beatles ashram this afternoon?’, I jump out of bed, even though I don’t have a clue what the Beatles ashram may be.
