仁王護國般若波羅蜜多經疏 3.316

3.316

解曰：言非住者，遍修諸行，不住止之。非不住者，於所修行心無散亂，常寂靜故。向一切智者，所修行願悉皆趣入一切智故。從此第三依地辨德。於中分四：且初第一魔不能動。

The commentary explains: Saying "neither abiding" means that they universally cultivate all practices without abiding or halting in them. "Nor not abiding" means that with regard to the practices cultivated, their minds are free of distraction and are ever tranquil. "Because they head toward all-knowledge" means that all the practices and vows they cultivate completely enter into all-knowledge. Hereafter, the third part distinguishes the virtues based on the stage. This is divided into four: first, Māra cannot shake them.
