A friend recently told me about a couple of blokes he’d heard about who’d taken a year out from their careers to go and seek the fountainhead of spiritual wellbeing. They spent time at a monastery. They went to Tibet and hung out with the Buddhists. They consulted shamans in South America and Zen masters in Japan. Eventually they learned the secret from a druid at Glastonbury, who’d found it, he said, on the back of a bottle of bleach: “Stand upright in a cool place.”
