The commentary states: From here below, the second part explains again point by point according to difficulties. That is to say, the previous text says "cultivate the mother of all buddhas' wisdom," or says "the root mother of wisdom of nature," whose characteristics are difficult to understand, so now it explains them again. The text has two distinct parts: first, explaining the principle-nature; later, below "bodhisattvas," explaining again. The text has two distinct parts: first, explaining the principle-nature; later, below "bodhisattvas," explaining again the practice-nature. This is the first. That is to say, what was previously called "the root mother of wisdom of nature" is precisely the prajñā of principle-nature within the bodies of the three vehicles, neither arising nor ceasing, its self-nature eternally abiding. Therefore, all sentient beings take this as the buddha-nature. Namely by this text, all sentient beings possess the tathatā buddha-nature; or alternatively, the bodhisattvas of the three vehicles are all called "awakening," using this true-mark prajñā as the nature of awakening for the three vehicles.
