6.89

又復經意雖愛、取緣，要因無明不了彼苦，方起愛、取。故無明發非愛、取發。雖作意時，如理相應，不起無明，由有彼種隨眠力故，令此不了上界為苦造不動等，故無明發。如二乘者有漏善心，不了於境，說由無明習氣力故，此亦如是。

Furthermore, the intent of the sūtra is that although craving and grasping are conditions, one must rely on ignorance that fails to understand that suffering before craving and grasping arise. Therefore, action is initiated by ignorance, not by craving and grasping. Although at the time of attention, it is associated with correct thinking and does not initiate [manifest] ignorance, due to the force of the latent propensity of those seeds, it causes one to fail to understand that higher realms are suffering and to create unmoving action, etc.; hence it is initiated by ignorance. Just as the sāsrava wholesome minds of the two vehicles fail to understand the object and are said to be due to the force of the impregnations of ignorance, this is likewise so.
