仁王般若經疏 2.138

2.138

From 'Great King' on is the third section within the response to the questions, determining the title of the sūtra and exhorting its upholding. The text has three parts: first, generally listing the sūtra's titles and exhorting people to uphold it; from 'further possesses immeasurable' on, second, revealing the functions of the sūtra; from 'You should' on, third, concluding by exhorting to uphold it. In the first part of listing titles, it says 'This sūtra is named The Sūtra of the Benevolent King Inquiring about Prajñā': this sūtra has two titles. If named after the person capable of requesting it, it is named The Sūtra of the Benevolent King's Inquiries; second, if established from its function, it is named The Sūtra of Protecting the State. By principle it generally protects against all decline, affliction, and the like, but since protecting the state is the principal theme, it is exclusively named 'Protecting the State'. Second, revealing the functions of the sūtra to make people delight in upholding it. Saying 'further possesses immeasurable merit' generally shows that the merits are vast and numerous. Below, it separately reveals four functions: first, protecting the state and also protecting the king's body; second, clarifying that it protects homes and also protects people's bodies; third, from 'this prajñāpāramitā' on, concludes that prajñā is the protection of the state; fourth, from 'like city walls' on, uses analogies to show the protection of the state. City walls and moats are like morality (śīla): high and prominent city walls symbolize the Great Vehicle; moats below the city walls, outside and small, symbolize the Lesser Vehicle. Both have the meaning of guarding against wrongdoing and halting evil. Partitions and stone walls are like concentration (samādhi), used for securing the body: broad partitions symbolize the Great Vehicle; small stone walls symbolize the Lesser Vehicle. Swords are like wisdom; spears and shields are like morality and concentration. Third, from 'You should' on concludes by exhorting to uphold it.
