維摩經玄疏 3.108

3.108

次明從罽那尸棄佛，至然燈佛，為二阿僧祇劫。是時，菩薩用七莖蓮華供養然燈佛，敷鹿皮衣，布髮掩泥，時然燈佛便授其記：「汝於來世，當得作佛，名釋迦牟尼。」爾時，菩薩雖自知——我必作佛，而口不稱「我當作佛」。今謂：得煖法智慧，修六波羅蜜也。

Next, clarifying from Śikhin Buddha to Dīpaṅkara Buddha constitutes the second asaṃkhyeya kalpa. At that time, the bodhisattva offered seven stalks of blue lotuses to Dīpaṅkara Buddha, spread out his deerskin robe, and laid out his hair to cover the mud. Then Dīpaṅkara Buddha bestowed the prophecy upon him: "In a future life you will attain buddhahood, named Śākyamuni." At that time, although the bodhisattva knew of himself: "I will definitely become a buddha," his mouth did not proclaim: "I will become a buddha." I now say: he had attained the wisdom of the dharma of warmth and cultivated the six pāramitās.
