God does work through both pure and impure vessels but that does not mean that one should keep nature impure for ever. When the vessel will become pure the urge for action coming from within will be a flawless, definitive action. As long as that does not happen one has to minimize one's activities.
Sri AurobindoEven if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
Sri AurobindoThe aggressive and quite illogical idea of a single religion for all mankind, a religion universal by the very force of its narrowness, one set of dogmas, one cult, one system of ceremonies, one ecclesiastical ordinance, one array of prohibitions and injunctions which all minds must accept on peril of persecution by men and spiritual rejection or eternal punishment by God, that grotesque creation of human unreason which has been the parent of so much intolerance, cruelty and obscurantism and aggressive fanaticism, has never been able to take firm hold of the Indian mentality.
