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.
Let the scripture be your authority in determining what should be done and what should not be done. You should perform your duty following the scriptural injunction.
Those who practice severe austerities without following the scriptures, with hypocrisy and egotism, impelled by lust, and attachment; / Senselessly torturing the elements in their body and also Me who dwell within the body; know these ignorant persons to be of demonic nature.
All beings follow their nature. Even the wise act according to their own nature. What, then, is the value of sense restraint?
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.
Because, if I do not engage in action relentlessly, people would follow My path in every way.
