‘The ignorant’ are those people who do not know the entire truth about the self; ‘attached to their work’ means they are inseparably yoked to work. Because of their incomplete knowledge of the self, they are not qualified for Jñana Yoga which is of the nature of practising knowledge of the self. They are qualified for Karma Yoga only. As they should practise Karma Yoga for the vision of the self in the same manner Karma Yoga should be practised by one who is recognised as virtuous, who is unattached to work by reason of the vision of the self, and who wishes that his conduct should give guidance to others in virtuous conduct. In this way he should protect the world from chaos by his example. Such a person, even though qualified for Jñana Yoga should practise Karma Yoga.
