Sri Aurobindo
Letters of Sri Aurobindo
Volume IV - Part 2
In spite of the outbreak of temper and violence with regard to the boy I do not think it can be said that you have not changed at all or made any progress. There are three obstacles that one has to overcome in the vital and they are very difficult to 
overcome, lust (sexual desire), wrath and rajasic ego. I think you have progressed much in all three. Even in regard to anger, the outbreaks are surely less common, less overpowering and long-continued than they were before. It has been so much in your vital nature that you have to be on your guard against fits like these coming back; you have also to overcome excitement and violence of speech; but if you persevere without being discouraged, the freedom will come. Rajasic ego is the ground of the others. I think your idea about X is good for this purpose. If you can accustom yourself to do as scrupulously work not attractive to you as you do what attracts you and to do it in accordance with the ideas and standards of another, not insisting on your own, that should be an excellent discipline for the rajasic ego and bring into the vital a greater power of self-giving and peace.
