He whose intellect is free from desires does not get caught in the bindings of the actions. A person attains the qualities of a sanyasi (renunciate) only when desires are given up. Therefore both Karma Sanyasa (renouncing actions) and Karmayoga (performing actions without desire for fruits) are the same.
Only ignorant persons think that the two (i.e. Jnana Yoga of the Sankhyas and Karmayoga) are different but those who have experienced Self know that they are not different.
A person who, after getting rid of desires, has become consciousness (Brahman) itself, pervades the expanse of the three worlds (i.e. heaven, earth and the nether) through the form of the Self, even by being at one place. For such a person. language like 'This is done by me' or 'I want to do this' becomes redundant and he remains a non-doer in spite of his actions. Because such a person is not even conscious of his body, even though his outward behavior and his bodily functions appear to be normal. Then how can he have the ego about his actions?
Once a person is convinced in his mind that God is a non-doer then the fundamental idea that 'He is not different from me' is naturally established. Once this sense has arisen in the mind then he does not see himself different from anything in the three worlds and considers the world to be as liberated as he is. Such persons have a sense of equability towards everything in this world. Such men of Knowledge do not notice differences between different creatures.
