Work done with no concern or desire for profit, purely out of love or from a sense of duty, is true yoga.

Work done with no concern or desire for profit, purely out of love or from a sense of duty, is true yoga. Such yoga destroys one's animal nature and transforms one into a divine being. Serving others, visualising them as Atmas, will help one to progress; it will save one from sliding down from the spiritual stage attained. Selfless service (seva) is far more salutary than even vows and worship (puja). Service disintegrates the selfishness latent in you; it opens the heart wide and makes the heart blossom. So work done with no desire is the supreme ideal; and when the mansion of life is built on that foundation, through the subtle influence of this basis of selfless service, virtues will gather unto the person. Service must be the outer expression of inner goodness. And, as one undertakes selfless service more and more, one's consciousness expands and deepens, and one's true (Atmic) reality is more clearly experienced.
