4.525

經　答曰（至）界性離故。

Sūtra: He answered: ["It is not an illness of the earth element, nor is it apart from the earth element; water, fire, and wind are also like this. Why? Because the illnesses of sentient beings arise from the four elements, and because I am ill due to their illnesses,] the nature of the elements is separated."
