1. You, human one, take a sharp sword. Use it like a razor and shave your head and beard. Then use scales to divide the hair.
2. At the end of the siege, burn one-third of it in the city. Strike another third with the sword left and right. Then scatter one-third to the wind and let loose the sword after it.
3. From that third, take a few strands and hide them in your garment.
