Śaṅkarācārya's commentary

The steady-minded man who, resolved that "I do actions for the sake of the Lord, not for my benefit," abandons the fruit of action attains the peace called mokṣa, as the result of devotion, through the following stages: first, purity of the mind; then, attainment of knowledge; then, renunciation of all actions; and lastly, devotion to knowledge. But he who is unsteady is led by desire and is attached to the fruit. He is firmly bound. Wherefore, be thou steady-minded.
