5.12

युक्तः कर्मफलं त्यक्त्वा शान्तिमाप्नोति नैष्ठिकीम् | अयुक्तः कामकारेण फले सक्तो निबध्यते ||५-१२||

yuktaḥ karmaphalaṃ tyaktvā śāntimāpnoti naiṣṭhikīm . ayuktaḥ kāmakāreṇa phale sakto nibadhyate ||5-12||

yuktaḥ
one who is engaged in devotional service
karma-phalam
the results of all activities
tyaktvā
giving up
śāntim
perfect peace
āpnoti
achieves
naiṣṭhikīm
unflinching
ayuktaḥ
one who is not in Kṛṣṇa consciousness
kāma-kāreṇa
for enjoying the result of work
phale
in the result
saktaḥ
attached
nibadhyate
becomes entangled

The steadily devoted soul attains unadulterated peace because he offers the result of all activities to Me; whereas a person who is not in union with the Divine, who is greedy for the fruits of his labor, becomes entangled.
