仁王經疏 3.115

3.115

Explanation: The second [section] is the Buddha manifesting supernormal transformations to cause the assembly to obtain benefit. Within this there are two: first, the Buddha manifests supernormal transformations; and later, the contemporary assembly obtains benefit. The former has two: first, stating the topic and adducing the number; and later, sequentially detailing them individually. This is the first. "Supernormal" (shen) refers to samādhi (equipoise), and "transformation" (bian) means altering. Due to the power of equipoise, altering is sovereign; hence it is called "supernormal transformation." "Inconceivable" means the mind cannot conceptualize it and words cannot discuss it; hence it is called inconceivable. Thus the Lotus Sūtra says: "It cannot be proclaimed by the mouth, nor can it be measured by the mind." The Dazhidulun says: "The sphere of mental activity is extinguished, and the path of speech is cut off." The Large Prajñāpāramitā says: "The path of mind and speech is cut off; it is called inconceivable."
