3.121

言唯取能發正感後世善惡業者，然此有四：一、相應；二、不共；三、纏；四、隨眠，皆能發業，外道內道異生放逸不放逸隨其所應用四無明發業皆別，如緣起經自廣分別。此中說行通身語意，唯善不善現行種子假色及思以為自性，此亦有三，感三果故。

Regarding the statement that it takes only that which is capable of initiating and directly bringing about wholesome and unwholesome karma of future lives: however, this has four [aspects]: first, associated; second, unassociated; third, active entanglements; fourth, latent proclivities. All of them can initiate karma. Non-Buddhists and Buddhists, ordinary beings, negligent and non-negligent, all initiate karma differently according to how they apply the four ignorances, as the Pratītyasamutpādasūtra itself distinguishes extensively. Here, 'formation' is said to encompass body, speech, and mind, and has as its intrinsic nature only the active states and seeds, designated form, and intention of wholesome and unwholesome; this also has three kinds, because it brings about three fruits.
