Bhagavad Gita: Verse 5.12
युक्तः कर्मफलं त्यक्त्वा शान्तिमाप्नोति नैष्ठिकीम् ।
अयुक्तः कामकारेण फले सक्तो निबध्यते ॥ ५-१२॥
yuktaḥ karmaphalaṃ tyaktvā śāntimāpnoti naiṣṭhikīm
ayuktaḥ kāmakāreṇa phale sakto nibadhyate
The united one (the well-poised or the harmonised) , having abandoned the fruit of action, attains Eternal Peace; the non-united (the unsteady or the unbalanced) , impelled by desire and attached to the fruit, is bound.
