6.36 Yoga is hard to attain even in spite of great efforts by one of unrestrained self, i.e., of unrestrained mind. But the same Yoga which is of the form of sameness of vision can be attained by proper means by one who is striving, whose 'mind is subdued,' i.e., by one whose mind is conered by works (Karma Yoga) taught before, which is of the nature of My worship and which includes within itself knowledge (Jnana). Then Arjuna puts estions in order to hear the greatness of Yoga, as it really is, which he has already heard about at the beginning of the teaching, 'Here there is no loss of effort' (2.40). There the greatness of Karma Yoga as inclusive of knowledge of the self with Yoga as its culmination was taught. This alone is the real greatness of Yoga.
