I can't really fault Dogen for his sentiments. But that bearded guy from India said the certain things to Emperor Wu immediately pointing to something profound. Peace, love, and understanding all come about in the same way as greed, ignorance, and hatred. It's more expeditious to practice one set than another. But regardless of which set is met, it's expeditious to maintain equanimity, though at times it can be awfully trying. Attachments are the ecosystem of flypaper in which we dwell.
Be careful out there.
It's easy to see how to screw up. It's harder not to screw up.
