“‘Brahmā Kumāra told King Vaiśravaṇa, “Why do you say, ‘The Tathāgata appeared in the world and teaches such a Dharma. It’s amazing, extraordinary, and unprecedented!’? The Tathāgata teaches what’s good and not good with the power of skillful means. The fully expressed Dharma doesn’t attain anything, but the empty and pure Dharma does attain something. This Dharma is sublime like ghee.”
