仁王般若經疏 1.10

1.10

Fourth, discerning the function of the sūtra. This sūtra takes the two protections, internal and external, as its function. As for the internal protection, the text below states: 'I expound for the bodhisattvas the causes and conditions for protecting the buddha-fruit and the causes and conditions for protecting the practice of the ten bhūmis.' As for the external protection, the text below states: 'I now expound for you the causes and conditions for protecting the state', causing the state to obtain security, the seven calamities not to arise, disasters not to be produced, and the myriad people to be peaceful and joyful; this is called external protection.
