This section is best summed up in two sentences; this one:
The Bodhisattva-Mahasattva is said to have grasped meaning well, when, all alone in a lonely place, he walks the path leading to Nirvana, by means of his transcendental wisdom (prajna) which grows from learning, thinking, and meditation, and causing a revulsion first at the source of habit-energy by his self-knowledge (svabuddhi), abides on the stages of self-realisation where he leads a life full of excellent deeds.
And this one:
Further, Mahamati, the Bodhisattva-Mahasattva who is conversant with words and meaning observes that words are neither different nor not-different from meaning and that meaning stands in the same relation to words.
Words only point the way. Although they arise from discrimination, they can lead out of it.
