建立曼荼羅及揀擇地法 1.37

1.37

掘地意者恐地中有穢物，如前所說灰炭、髑髏、蟲窠、樹根、毒螫之類，或有古墓、伏屍。若惡物苦多不堪建立，應當捨棄更求勝處；若無此過，但掘深一肘二肘或深三肘，其土運出細打揀擇；若穿至地床未曾掘處，知地必淨心復不疑，不論深淺即不須掘；若土色有雜不相似者亦須除去，別取河岸淨土替之，如法填治，每填土一重即以加持香水一灑，乃至填滿皆如是作。填土滿已築令堅實平如鏡面。

The purpose of digging the ground is the fear that there may be defilements in the earth, such as the aforementioned ashes, charcoal, skulls, insect nests, tree roots, stinging vermin, and the like, or ancient graves and hidden corpses. If there are too many bad objects, it is unsuitable for establishment; one should abandon it and seek another, better place. If there are no such faults, one merely digs down one cubit, two cubits, or three cubits deep, carries out the soil, crushes it fine, and sifts it. If one digs down to the bedrock where it has never been excavated before, knowing that the ground is surely pure and having no doubt in mind, regardless of the depth, one does not need to dig further. If the color of the earth is mixed and inconsistent, it must also be removed and replaced with pure soil taken from a riverbank, filled and treated according to the ritual. Each time a layer of soil is filled in, it is sprinkled once with consecrated scented water, and one proceeds in this manner until it is completely filled. When the filling of the earth is complete, tamp it so that it is firm and level as a mirror.
