4.108

五七遍呪水，以葦桶柱陰上，以水從桶中七遍呪水一唾之末，後以一掬水望面灑之。

Empower water with the spell five times seven times. Place a reed tube leaning against the genitals; using the water, through the tube, empower the water with the spell seven times, spit it out once, and finally take a handful of water and sprinkle it toward the face.
