按彼論云：色、味、香、觸同類為因者，謂二微果等和合。釋二微果等和合之色，從彼極微色等而生，極微色等是微果色同類因故，故論復云：極微色等能造同類，二微等色同類果故。

According to that treatise: "Form, taste, smell, and contact having a homogeneous cause refers to the aggregate of the dyad effect and so forth." This explains that the form of the aggregate of the dyad effect and so forth arises from the form and so forth of those atoms, because the form and so forth of the atoms are the homogeneous cause of the form of the dyad effect. Therefore, the treatise further says: "The form and so forth of the atoms can produce their homogeneous kind, because the form of the dyad and so forth is a homogeneous effect."
