नियतं कुरु कर्म त्वं कर्म ज्यायो ह्यकर्मणः ।शरीरयात्रापि च ते न प्रसिद्ध्येदकर्मणः ॥
niyataṃ kuru karma tvaṃ karma jyāyo hyakarmaṇaḥśarīrayātrāpi ca te na prasiddhyedakarmaṇaḥ
Do thou do controlled action, for action is greater than inaction; even the maintenance of thy physical life cannot be effected without action.
Gītā 3·8Not formal works fixed by an external rule, but desireless works controlled by the liberated buddhi, is the Gita’s teaching.
Buddhiyoga is fulfilled by karmayoga; the Yoga of the self-liberating intelligent will finds its full meaning by the Yoga of desireless works. Thus the Gita founds its teaching of the necessity of desireless works, niṣkāmakarma and unites the subjective practice of the Sankhyas—rejecting their merely physical rule—with the practice of Yoga.
