金光明最勝王經疏 3.486

3.486

贊曰：帝釋啟請，有四：一請法儀、二所請主、三所為機、四所請法。此初二。初中三：一能請人、二所承力、三正軌則。

The commentary says: Śakra's petition has four parts: first, the etiquette of requesting the Dharma; second, the master of whom it is requested; third, the recipients on whose behalf it is requested; fourth, the Dharma that is requested. Here are the first two. Within the first there are three: first, the person able to request; second, the power that is received; third, the proper protocol.
