1. Now the cure for headache.
2. Having moistened his hands, he passes them over his eye-brows with (the verse), 'From the eyes, from the ears, from the whiskers, from the chin, from the forehead, I drive away this disease of the head.'
3. If (only) one side (of the head aches, he recites the verse), 'Cleaver! Thou with the disfigured eyes! White-wing! Renowned one! And thou with the various-coloured wing! Let his head not ache.'
4. Then it will get better.
