Bhagavad Gita 5.23शक्नोतीहैव यः सोढुं प्राक्शरीरविमोक्षणात्।कामक्रोधोद्भवं वेगं स युक्तः स सुखी नरः ॥

Yukta means harmonised or steadfast in Yoga or selfabiding.Desire and anger are powerful enemies of peace. It is very difficult to annihilate them. You will have to make very strong efforts to destroy these enemies.When the word Kama (desire) is used in a general sense it includes all sorts of desires. It means lust in a special sense.While still here means while yet living. The impulse of desire is the agitation of the mind which is indicated by hairs standing on end and cheerful face. The impulse of anger is agitation of the mind which is indicated by fiery eyes, perspiration, biting of the lips and trembling of the body. In this verse you will clearly understand that he who has controlled desire and anger is the most happy man in this world, nor he who has immense wealth, a beautiful wife and beautiful children. Therefore you must try your level best to eradicate desire and anger, the dreadful enemies of eternal bliss.Kama (desire) is longing for a pleasant and agreeable object which gives pleasure and which is seen, heard of, or remembered. Anger is aversion towards an unpleasant and disagreeable object which gives pain and which is seen, heard or, or remembered.A Yogi controls the impulse born of desire and anger, destroyes the currents of likes and dislikes,and attains to equanimity of the mind, by resting in the innermost Self, and so he is very happy.(Cf.VI.18)
