"# To professors of Sakara, "freedom from the four extremes" means understanding that the object of cognition exists in a momentary mode, empty of thought-constructions and lacking objectification."

"# "Middle way" is defined [by professors of Nirakara] in terms of a self-awareness that is not nil; it appears as blue, etc. objects, but characteristics do not arise in it."

"# To professors of Mayopamadvaya, "freedom from the four extremes" is [to know that] the characteristics are false, and [in reality] clear light. The following system had evidence for its beliefs."

"# To know the emptiness of objects is to know emptiness free of appearance and free of coverings. That is the Middle Way from which the "subsequent" or conventional has been purged."
