On Portents or Public Calamity (utpāta-adyāya) - Verse 9

If on festive occasions the car, the axle, the wheel, the yoke, or the flag should break or fall, or if any of them should be found to have been removed from its place and another put in its stead, or if the tie should break and the parts get loose or if the car should stick into the ground and refuse to move, the king will suffer with his country.
