Grev and I spent a few minutes in amongst the tourists staring at the stained oil-walls and raked gravel of Ryoan-ji's world-famous zen garden. Many of the men and women will be here for an eternity trying to unlock the secrets of the heart, but we knew something they didn't... that the truth and beauty of understanding is a lot more likely to come from the beautiful moss forests and serene mandarin lake than gardens of sand. Sometimes nature is a far better teacher than the ideas of man. Peace out.
