首楞嚴義疏注經 5.73

5.73

此顯速疾能至大覺，故一念不生即名為佛。超過地位劫數之說，如前文云「歇即菩提」，《圓覺》亦云「離幻即覺，亦無漸次。」皆斯義也。然至覺時，亦無自果可為所得，故云超無學耳。亦是約遲速校量，故說為超，非是都越地位直至無上覺耳。

This reveals that one can swiftly reach great awakening, so that when a single thought does not arise, one is named a Buddha. This surpasses the explanations of stages and eons; as the text stated earlier, "Ceasing is bodhi," and the Perfect Enlightenment Sūtra also says: "Free of illusion is awakening; there are no gradual steps." All share this meaning. Yet when one reaches awakening, there is also no fruit of one's own that can be attained; hence it says "transcends no-more-learning." It is also spoken of as "transcending" by way of comparing speed and slowness, not that one literally skips stages straight to unexcelled awakening.
