Bhagavad Gita 5.12

युक्तः कर्मफलं त्यक्त्वा शान्तिमाप्नोति नैष्ठिकीम्।अयुक्तः कामकारेण फले सक्तो निबध्यते ॥५.१२॥

yuktaḥ karmaphalaṃ tyaktvā śāntimāpnoti naiṣṭhikīmayuktaḥ kāmakāreṇa phale sakto nibadhyate

The one who is united (the well-poised or harmonized) having abandoned the fruit of action attains eternal peace; whereas the one who is not united (the unsteady or unbalanced), impelled by desire and attached to the fruit, is bound.
