Sri Aurobindo on Money as a Divine Force
Money is the visible sign of a universal force, and this force in its manifestation on earth works on the vital and physical planes and is indispensable to the fullness of the outer life. In its origin and its true action it belongs to the Divine. But like other powers of the Divine it is delegated here and in the ignorance of the lower Nature can be usurped for the uses of the ego or held by Asuric influences and perverted to their purpose. This is indeed one of the three forces — power, wealth, sex — that have the strongest attraction for the human ego and the Asura and are most generally misheld and misused by those who retain them. The seekers or keepers of wealth are more often possessed rather than its possessors; few escape entirely a certain distorting influence stamped on it by its long seizure and perversion by the Asura. For this reason most spiritual disciplines insist on a complete self-control, detachment and renunciation of all bondage to wealth and of all personal and egoistic desire for its possession. Some even put a ban on money and riches and proclaim poverty and bareness of life as the only spiritual condition. But this is an error; it leaves the power in the hands of the hostile forces. To reconquer it for the Divine to whom it belongs and use it divinely for the divine life is the supramental way for the Sadhaka.
You must neither turn with an ascetic shrinking from the money power, the means it gives and the objects it brings, nor cherish a rajasic attachment to them or a spirit of enslaving self-indulgence in their gratifications. Regard wealth simply as a power to be won back for the Mother and placed at her service.
All wealth belongs to the Divine and those who hold it are trustees, not possessors.
