然而文中說眼色識界等十八種法亦名界者，相從亦為界非正界體，故此又言十八種法從別別界別別種子別別種姓生起出現，故知十八種法非正界體，界與種子種姓三種名異體同，同是種子為十八界體，今將了知十八種法種子各別名界善巧，即於四緣中同於因緣而得善巧。

However, where the text states that the eighteen dharmas, such as the eye, visible forms, and visual consciousness elements, are also called elements (dhātu), they are termed elements only by extension and are not the actual substance of an element. Therefore, the text also says that these eighteen dharmas arise and appear from distinct elements, distinct seeds, and distinct gotras. From this one knows that the eighteen dharmas are not the actual substance of an element. Element, seed, and gotra are different in name but identical in substance: they are identically seeds that constitute the substance of the eighteen elements. Now, knowing that the seeds of the eighteen dharmas are distinct is called skill in the elements, which is to attain skill in the identical causal condition (hetu-pratyaya) among the four conditions.
