2.132

天曰。我無得無證故辯如是　答文二。此初正答。二乘捨縛求脫故有得證。大士悟縛脫平等非縛非脫故無得無證。既智窮不二之門故辯無礙也。

The goddess said: "It is because I have neither attainment nor realization that my eloquence is like this." (The reply has two parts. This is the first, the direct reply. The two vehicles abandon bondage to seek liberation, and so they have attainment and realization. Mahāsattvas awaken to the equality of bondage and liberation, being neither bound nor liberated, and therefore have neither attainment nor realization. Having exhausted the gate of non-duality with their wisdom, their eloquence is unobstructed.)
