Bhagavad Gita Asa It Is Chapter 12 Text 10-12

If you cannot practice the regulations of bhakti-yoga, then just try to work for Me, because by working for Me you will come to the perfect stage.
Text 10
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.
Text 11
If you cannot take to this practice, then engage yourself in the cultivation of knowledge. Better than knowledge, however, is meditation, and better than meditation is renunciation of the fruits of action, for by such renunciation one can attain peace of mind.
