俱舍論疏 2.16

2.16

The treatise says: "If a phenomenon has objective opposition... is the fourth alternative." This is the seventh [section], which analyzes the tetralemma. Within the passage there are two parts: first, the tetralemma of objective opposition against obstructive opposition; second, the subsequent-affirming proposition (anuloma) of objective opposition against cognitive opposition. This is the first. The first alternative is having objective opposition and not obstructive; the second alternative is having obstructive and not objective; the third is both; the fourth is neither; all are readily understood.
