6.1 The Lord said  He who, without depending on such fruits of works as heaven, etc., performs them, reflecting, 'The performance of works alone is my duty (Karya). Works themselves are my sole aim, because they are a form of worship of the Supreme Person who is our Friend in every way. There is nothing other than Him to be gained by them' - such a person is a Sannyasin, i.e., one devoted to Jnana Yoga, and also a Karma Yogin, i.e., one devoted to Karma Yoga. He is intent on both these, which is the means for attaining Yoga, which is of the nature of the vision of the self.

'And not he who maintains no sacred fires and performs no works,' i.e., not he who is disinclined to perform the enjoined works such as sacrifices, etc., nor he who is devoted to mere knowledge. The meaning is that such a person is devoted only to knowledge, whereas a person who is devoted to Karma Yoga has both knowledge and works.

Now Sri Krsna teaches that there is an element of knowledge in the Karma Yoga as defined above.
