瑜伽論記 7.360

善知瑜伽即善知方便者，以智行與理相應，因智行能與果照相應故智名方便，即亦號相應也。

'Skilled in knowing yoga' means skilled in knowing means, because the practice of wisdom is in conjunction with principle; since the causal practice of wisdom can be in conjunction with the illumination of fruition, wisdom is called 'means', and is thus also named 'conjunction'.
