法華玄論 4.169

4.169

答：通皆例然，但不著有則易、不證空則難。方便能令不證空，故與其巧名。譬如四河合流同注海口，非大力龍莫自能變；三解脫俱流注涅槃海，非方便大力莫能不證。以方便大力有變無之巧不墮二乘，故與其巧名也。

Answer: In a general sense all are analogous. However, not clinging to existence is easy, whereas not realizing emptiness is difficult. Because skillful means can cause one not to realize emptiness, the name "skillful" is given to it. For example, when the four rivers converge and flow together into the mouth of the sea, none other than a dragon of great strength can divert them of itself; the three liberations flow together into the sea of nirvāṇa, and none other than the great power of skillful means can prevent realization. Because the great power of skillful means has the skill to transform nonexistence into existence so that one does not fall into the two vehicles, the name "skillful" is given to it.
