16.4

釋曰：初兩句標，次四句釋。論云：「佛依業果性類不同，所治能治殊，說黑黑等四（前三業果殊，第四所治能治殊也）。」

Explanation: The first two lines introduce, and the subsequent [lines] explain. The treatise states: "Based on the differences in the nature and classes of karma and its fruit, and the distinction between what is to be countered and the counteragent, the Buddha spoke of four [karmas], black-black and the rest (the first three differ in karma and fruit; the fourth differs as what is to be countered and the counteragent)."
