A short compilation of passages on Karma Yoga from Sri Aurobindo
All spiritual paths lead to a higher consciousness and union with the Divine and among the many paths one of the greatest is the Way of Works: it is as great as the Way of Bhakti or the Way of Knowledge.

The only work that spiritually purifies is that which is done without personal motives, without desire for fame or public recognition or worldly greatness, without insistence on one’s own mental motives or vital lusts and demands or physical preferences, without vanity or crude self-assertion or claim for position or prestige, done for the sake of the Divine alone and at the command of the Divine. All work done in an egoistic spirit, however good for people in the world of the Ignorance, is of no avail to the seeker of the Yoga.

Self-dedication does not depend on the particular work you do, but on the spirit in which all work, of whatever kind it may be, is done. Any work, done well and carefully as a sacrifice to the Divine, without desire or egoism, with equality of mind and calm tranquillity in good or bad fortune, for the sake of the Divine and not for the sake of any personal gain, reward or result, with the consciousness that it is the Divine Power to which all work belongs, is a means of self-dedication through Karma.

Of course the idea of bigness and smallness is quite foreign to the spiritual truth. Spiritually there is nothing big or small. Such ideas are like those of the literary people who think writing a poem is a high work and making shoes or cooking the dinner is a small and low one. But all is equal in the eyes of the Spirit — and it is only the spirit within with which it is done that matters. It is the same with a particular kind of work, there is nothing big or small.

There are many who pursue inwardly the spiritual life and keep the family duties, not as social duties but as a field for the practice of karmayoga, others abandon everything to follow the spiritual call alone and they are justified if that is necessary for the Yoga they practise or if that is the imperative demand of the soul within them.

It is not the form of the work itself or mere activity but the consciousness and Godward will behind it that are the essence of Karmayoga; the work is only the necessary instrumentation for the union with the Master of works, the transit to the pure Will and power of Light from the will and power of the Ignorance.
