युक्तः कर्मफलं त्यक्त्वा शान्तिमाप्नोति नैष्ठिकीम्।
अयुक्तः कामकारेण फले सक्तो निबध्यते।।5.12।।
5.12 Giving up the result of work by becoming resolute in faith, one attains Peace arising from steadfastness. One who is lacking in resolute faith, being attached to the result under the impulsion of desire, becomes bound.
5.12 A Yogin is one who has no hankering for fruits other than the self, and who is exclusively devoted to the self. If a man renounces the fruits of actions and performs actions merely for the purification of himself, he attains lasting peace, i.e., he attains bliss which is of the form of lasting experience of the self. The unsteady person is one who is inclined towards fruits other than the self. He has turned himself away from the vision of the self. Being impelled by desire, he becomes attached to fruits of actions, and remains bound for ever by them. That is, he becomes a perpetual Samsarin or one involved in transmigratory cycle endlessly. What is said is this: Free of attachment for fruits and attributing ones actions to Prakrti which has developed into the form of senses, one should perform actions merely to free the self from bondage. Next, the shifting of agency to Prakrti, from which the body has come into existence, is described:
Yuktah karmaphalam tyaktwaa shaantim aapnoti naishthikeem; Ayuktah kaamakaarena phale sakto nibadhyate.
yuktaḥ—one who is united in consciousness with God; karma-phalam—the results of all activities; tyaktvā—giving up; śhāntim—peace; āpnoti—attains; naiṣhṭhikīm—everlasting; ayuktaḥ—one who is not united with God in consciousness; kāma-kāreṇa—impelled by desires; phale—in the result; saktaḥ—attached; nibadhyate—becomes entangled
