大佛頂如來放光悉怛多般怛羅大神力都攝一切呪王陀羅尼經大威德最勝金輪三昧呪品 1.77

1.77

「作此印，承呪水七反，嗽口齒并飲灑掃，解一切金剛鬼神。喫兩手反合掌背相著，當想嗔怒，誦呪二七遍已，急翻兩手正合掌已，又誦七遍，即以兩手急攉開之。」

Making this mudrā, receive the water empowered seven times, rinse the mouth and teeth, drink, and sprinkle/sweep [the ground]; this releases all vajra ghosts and spirits. Inverting both hands with their backs pressed against each other, visualize wrath; having recited the mantra two times seven (fourteen) times, quickly flip both hands into a proper palm-to-palm clasp, and having recited it seven more times, quickly tear both hands open.
