「以無發業至有覆無記表」者，雙答。以無發業等起心故者，此即總答。有尋伺心能發表業，二定已上都無此心，是故表業上三地都無。問：何故上地無尋伺心？《婆沙》云「尋伺麁動不寂靜，上地微細寂靜故（已上論文）。」又發表心唯修所斷，外門轉故。見所斷惑，內門轉故，不能發業。欲界雖有身、邊二見，有覆無記見所斷攝，內門轉故不能發業。以欲定無有覆無記修所斷惑，是故欲界中無有覆無記表。此即顯別。

Regarding "Because there is no origination-mind that initiates karma... concealed-unspecified manifestation": this is the dual answer. "Because there is no origination-mind that initiates karma" is the general answer. A mind with investigation and examination is able to produce manifest karma; from the second dhyāna upward there is no such mind at all, and therefore manifest karma does not exist in the higher three planes. Question: Why do the higher planes lack minds with investigation and examination? The Mahāvibhāṣā states: "Investigation and examination are coarse, agitated, and not calm; the higher planes are subtle and calm" (end of treatise citation). Furthermore, the mind that initiates karma is abandoned only by cultivation, because it operates toward external gates. Afflictions abandoned by seeing operate toward internal gates; therefore they cannot initiate karma. Although the Desire Realm possesses the two views of self and extreme, they are subsumed under concealed-unspecified [afflictions] abandoned by seeing; operating toward internal gates, they cannot initiate karma. Because the Desire [Realm] definitely lacks concealed-unspecified afflictions abandoned by cultivation, there is no concealed-unspecified manifestation in the Desire Realm. This shows the distinction.
