The Dhammapada, too, is a collection – traditionally, sayings of the Buddha, one of the very greatest of these explorers of consciousness. In this case the messages have been sorted, but not by a scheme that makes sense to us today. Instead of being grouped by theme or topic, they are gathered according to some dominant characteristic like a symbol or metaphor – flowers, birds, a river, the sky – that makes them easy to commit to memory. If the Upanishads are like slides, the Dhammapada seems more like a field guide. This is lore picked up by someone who knows every step of the way through these strange lands. He can’t take us there, he explains, but he can show us the way: tell us what to look for, warn about missteps, advise us about detours, tell us what to avoid. Most important, he urges us that it is our destiny as human beings to make this journey ourselves. Everything else is secondary.
