金剛三昧經論 2.18

2.18

The sūtra states: 'Good son! The nature and marks of this mind are, furthermore, like an āmalaka fruit: it originally does not arise from itself, does not arise from other, does not arise from both, does not arise uncaused, and is without arising. Why is this? Because conditions replace and expire. Dependent arising is not arising; the expiration of conditions is not cessation. Concealment and manifestation are signless; roots and trunk are quiescent and extinguished. It is in no place, and its abiding is not seen, because it is of a determinate nature.'
