The Buddha sings these verses to Superior-Practice Bodhisattva in Chapter 21 of the Lotus Sūtra:

Anyone who keeps this sūtra
Will be able to expound
The meanings of the teachings,
And the names and words [of this sūtra].
Their eloquence will be as boundless
And as unhindered as the wind in the sky.

Anyone who believes in and upholds the Lotus Sutra, which is transmitted from Sakyamuni, has a thorough knowledge of the meanings of its diverse teachings, words, and interpretations, and is able to expound them impartially, just as the wind sails freely through the sky. That person will be able to reach a stage of freedom, and remain there.
