When the bloke from the removal firm came the other day to give me a quote for shifting my furniture and possessions to Earls Barton, he looked everything over and commented: "You travel light, don't you?"

The same day I heard an interview on the radio with the French translator of the Dalai Lama. He was being quizzed about the Buddhist concept of renunciation. He likened life to an uphill climb with a rucksack on your back. Half the contents of the rucksack are your provisions, the other half are rocks; and the higher you climb, the harder the rocks make your journey. Renunciation is simply a matter of stopping for a moment, and emptying your rucksack of its rocks.

My rocks are all in my head. So how do you put that down?
