無量壽經優婆提舍願生偈註 2.138

2.138

知進守退曰智，知空無我曰慧。依智故不求自樂，依慧故遠離我心貪著自身。

Knowing when to advance and observing when to retreat is called jñāna (intellect); knowing emptiness and selflessness is called prajñā (insight). By relying on intellect, he does not seek his own pleasure; by relying on insight, he stays far away from his ego-centered mind and greedily clinging to his own person.
