大輪金剛陀羅尼一
Mahacakra Vajra Dharani 1
訥謨薩怛唎耶 地毘迦喃 怛他揭多喃唵毘囉 時毘囉時 摩訶斫迦囉 跋闍唎薩多薩多娑囉帝娑囉帝 怛唎曳怛唎曳毘陀末儞 三槃若儞 怛囉末底悉陀阿揭唎怛炎 娑婆訶
誦此陀羅尼三七遍，即當入一切漫荼羅(壇也)，所作皆成(誦呪。有身印手印，作印誦呪法即易成。若未入壇，不得輙作。今令誦此呪，即當入壇作印行，不成盜法也)。
Recite this mantra twenty-one times, and it will count as entering all mandalas(sacred ritual spaces). All practices will then be accomplished(Reciting mantras has body postures and hand gestures (mudras). Using these gestures with mantra recitation makes practice easier. However, if you have not yet entered a mandala, you should not casually perform these gestures. By reciting this mantra, you are effectively entering the mandala and may perform gestures without committing the fault of conducting uninitiated practices.).
