“Chahi, bhikkhave, aṅgehi samannāgato rañño bhadro assājānīyo rājāraho hoti rājabhoggo, rañño aṅgantveva saṅkhaṁ gacchati. Katamehi chahi? Idha, bhikkhave, rañño bhadro assājānīyo khamo hoti rūpānaṁ, khamo saddānaṁ, khamo gandhānaṁ, khamo rasānaṁ, khamo phoṭṭhabbānaṁ, javasampanno ca hoti. Imehi kho, bhikkhave, chahi aṅgehi samannāgato rañño bhadro assājānīyo rājāraho hoti rājabhoggo, rañño aṅgantveva saṅkhaṁ gacchati.
The Thoroughbred (3rd)
“Mendicants, a fine royal thoroughbred with six factors is worthy of a king, fit to serve a king, and is reckoned a factor of kingship. What six? It’s when a fine royal thoroughbred can endure sights, sounds, smells, tastes, and touches. And it’s fast. A fine royal thoroughbred with these six factors is worthy of a king, fit to serve a king, and is reckoned a factor of kingship.
