Early Buddhism

At Nāḷandā

Nālandasutta

Sāriputta boldly claims that no-one has ever, or will ever, be more enlightened than the Buddha. He admits that he cannot read the minds of all the Buddhas, but he understands a principle of the Dhamma: all those who become awakened do so by giving up the five hindrances, practicing the four kinds of mindfulness meditation, and developing the seven awakening factors.
