維摩經玄疏 3.109

3.109

次明從然燈佛，至毘婆尸佛，為第三阿僧祇劫滿。是時菩薩內心了了，自知作佛，口自發言，無所畏難：「我於來世，當得作佛。」今謂：此是頂法智慧，行六波羅蜜也。

Next, clarifying from Dīpaṅkara Buddha to Vipaśyin Buddha fulfills the third asaṃkhyeya kalpa. At that time the bodhisattva clearly understood in his inner mind, knowing of himself that he would become a buddha, and spoke forth from his mouth without fear or hesitation: "In a future life I will attain buddhahood." I now say: this is the wisdom of the dharma of the peak, practicing the six pāramitās.
