瑜伽論記 20.31

20.31

In explaining the first gateway, 'If there were no parikalpita, what fault would there be?', the answer states: 'In the paratantra nature, there would be no grasping of nominal conventions, etc.' From the past until now, grasping has always arisen with respect to nominal conventions on the paratantra; through the construction of grasping, the defiled dharmas of saṃsāra of that paratantra arise; by cutting off defilement, purity is attained. If this nature did not exist, there would be no grasping of nominal conventions. If this did not exist, defilement and purity could not be known. The faults regarding the absence of the latter two natures can be understood [accordingly].
