A person is said to have attained yogic perfection when there is no desire for sensual pleasures, or attachment to the fruits of work, and has renounced all personal selfish motives.

The one who remains the same towards friend or foe, in honor or disgrace, in heat or cold, in pleasure or pain; who is free from attachment is dear to me.

Always perform your duty efficiently and without attachment to the results, because by doing work without attachment one attains the Supreme.

Better indeed is knowledge than mechanical practice. Better than knowledge is meditation. But better still is surrender of attachment to results, because there follows immediate peace.

Knowledge is better than mere ritualistic practice, meditation is better than mere knowledge, renunciation of the fruit of work is better than meditation, peace immediately follows the renunciation of (the attachment to) the fruit of work.
