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 AurobindoThe Truth-power must be brought down from above into that state of peace, and this higher power - Parashakti - will directly guide the vehicle - ฤdhฤra - and transform it.
