Bhagavad Gita · 5.3

ज्ञेयः स नित्यसन्न्यासी यो न द्वेष्टि न काङ्क्षति।निर्द्वन्द्वो हि महाबाहो सुखं बन्धात्प्रमुच्यते॥

jñeyaḥ sa nitya-sannyāsī yo na dveṣhṭi na kāṅkṣhati nirdvandvo hi mahā-bāho sukhaṁ bandhāt pramuchyate

One who neither hates nor desires the fruits of actions is known as a perpetual renunciant. Free from all dualities, O mighty-armed Arjuna, such a person is easily liberated from bondage.
