7.117

五七遍呪水，以葦筒柱陰上，以水從桶中七遍呪，一唾之末後，以掬水望面灑之。

Empower water by chanting the mantra five times seven [thirty-five] times; lean a reed tube against the private parts, empower the water in the tube by chanting the mantra seven times, spit it out once, and finally scoop up a handful of water and sprinkle it toward the face.
