2.20

居士。是疾何所因起。其生久如。當云何滅　此下二宣已倩問也。文二。先問其化權疾。後問所化實疾。前中復三。一問現疾因起。二問室空無侍。三窮疾本相。初有問答。此問也。肇曰。使命既宣故復問疾之所由生也。疾因何而起。起未久近。云何而得滅乎。

"'Householder, from what cause did this illness arise? How long has it been present? How will it be extinguished?'"—from here down is the second, declaring his own feelings to inquire. The text has two parts: first inquiring into his transformed expedient illness, then inquiring into the actual illness that is transformed. The former again has three parts: 1. inquiring into the causes and conditions of the manifested illness; 2. inquiring into the empty room without attendants; 3. investigating the fundamental characteristic of the illness. The first has question and answer. This is the question. Sengzhao says: "The commission having been declared, he therefore further inquires into the origin of the illness: from what cause did the illness arise? How long ago did it arise? How can it be extinguished?"
