In a dry, barren landscape there are people lying on mounds of sand. I can’t be certain whether they are even alive. One of them, a child, rolls over and looks at me. A graceful golden fish emerges from a cactus blossom. The petals become the flowing tail of the fish. I am amazed at the brilliant resilience of this – how the fish has found the only water for miles around deep within the heart of the cactus.
