天台四教儀 1.16

1.16

次說般若，轉教、付財、融通、淘汰。此般若中不說藏教，帶通、別二，正說圓教。約時則禺中時（第四時）；約味則從生酥出熟酥。此從方等之後出《摩訶般若》（四熟酥味）。〈信解品〉云：「是時長者有疾，自知將死不久，語窮子言：『我今多有金銀珍寶，倉庫盈溢，其中多少所應取與。』」此領何義？答：明方等之後次說般若，般若觀慧即是家業。空生、身子受勅轉教，即是領知等也。

Next, he preached Prajñā: rotating the teaching, entrusting the wealth, integration, and weeding out. In this Prajñā, he did not preach the Tripiṭaka teaching; carrying along the shared and distinct, he primarily preached the perfect teaching. In terms of period, it is mid-morning (the fourth period); in terms of flavor, from raw butter comes clarified butter—here, following Vaipulya comes the Mahāprajñā (the fourth, the clarified butter flavor). The 'Belief and Understanding' chapter states: 'At that time the elder was ill, and knowing he would die before long, he addressed the poor son, saying: "I now possess abundant gold, silver, and precious gems; the storehouses are brimming over. You are to know the quantities of what should be taken and given."' What meaning does this convey? The answer is: this clarifies that after Vaipulya, he next preached Prajñā; the contemplative wisdom of Prajñā is precisely the family estate. Subhūti and Śāriputra receiving the command to rotate the teaching is precisely their taking charge and understanding, and so forth.
