athaitad apy asakto ’si
kartum mad-yogam asritah
tatah kuru yatatmavan

"If, however, you are unable to work in this consciousness of Me, then try to act giving up all results of your work and try to be self-situated."

Yata atmavan = controlling the mind, controlling senses, kuru = do, sarva'karma'phala-tyagam = sacrificing results of all actions. We have seen this sacrifice of results earlier. Kartrutva buddhi tyagam, manasa tyagam and phalatyagam - avoiding the thought that we were doing tha action, action is oursattitude and the thought we are doing the action for an inferior result should all be abandoned. Do only to realize atman sakshatkaram. What the Lord told earlier is now termed as srva karma phala tyagam. It means, with this determination, doing karma yoga is Karma yoga anushtanam. Atha =if, tad = that [service to God - mad karma in sloka 10], apy = even, asakto'si = is not capable of , kartum = doing, mad-yogam =Bhakti yoga in Me [Sri Krishna], asrita = attain. That means, person, incapable of doing even the initial actions like going to temples, singing His names, etc., meant for the very beginning of Bhakti yoga, should indulge in Karma yoga, to realize atman, with Bhakti in Him, and then the Lord. We should be careful here. The Lord says that with devotion to Lord, one should do Karma yoga. Because, if the person does Karma yoga only for atman sakshatkaram, then it would lead him to Kaivalyam or experiencing self atman. The Lord's objective is not that. He wants Arjuna to have Him as the objective. He wants Karma yoga to be praciced with Bhakti in Him. That is Karma yoga, then Atman sakshatkaram, then atman's true nature, then service to the Lord, then meditating on His aurpicious qualities, then confidence in Him and then finally realization of Him. Now, Arjuna seems to have another doubt: whether easening of efforts would also result in lesser benefits? The Lord assuages that doubt also in sloka 12.
