成唯識論了義燈 6.166

6.166

准六十八云：空行、無我行見名空行，餘行見名無願行，一行見名無相行，謂於滅諦離繫行見。此意即說，空無我行是空行，無常、苦、集、道八是無願行，滅諦下四，是無相行。此意道諦是有為故，屬無願行。餘義准前，此第二復次。

In accordance with fascicle sixty-eight: "The views of the practice of emptiness and the practice of non-self are called practices of emptiness; the views of the remaining practices are called wishless practices; the view of one practice is called signless practice, namely the view of the practice of disjunction regarding the truth of cessation." The meaning here is that the practices of emptiness and non-self are practices of emptiness; impermanence, suffering, origination, and the path—eight—are wishless practices; the four under the truth of cessation are signless practices. The meaning here is that because the truth of the path is conditioned, it belongs to wishless practices. The remaining points are in accordance with the above. This is the second alternative.
