金剛般若經贊述 2.285

2.285

Asaṅga says: “Do not entertain this thought” is an exhortation not to give rise to the preceding thought—namely, attaining the dharmakāya by taking marks as the cause. Why is this? Because the Tathāgata does not attain bodhi by taking the perfection of marks as the cause. Hence the commentary says that because marks are material in nature, one must take wisdom as the cause to only then attain bodhi, and not use marks, because marks are matter.
