由彼隨順所未斷故，三禪樂受是壞苦，四禪捨受是行苦，如是樂捨二受，外道執為我故，壞行二苦隨順所未斷，謂我當無，於不應怖妄生怖畏，樂捨二受本非是我，但是壞行二苦，今厭離彼非除於我，何勞生怖。

Because what accords with them has not yet been severed: the pleasurable feeling of the third dhyāna is the suffering of change, and the equanimous feeling of the fourth dhyāna is the suffering of conditioned formations. Because non-Buddhists grasp such pleasant and equanimous feelings as a self, what accords with the two sufferings of change and conditioned formations is not yet severed, and they think 'I shall cease to exist', falsely generating terror toward what should not be feared. The two feelings of pleasure and equanimity are originally not a self; they are merely the two sufferings of change and conditioned formations. Now, revulsion toward them does not eliminate the self, so why trouble oneself to generate fear?
