Bases of Yoga
You should not allow yourself to be discouraged by any persistence of the movements of the lower vital nature. 
There are some that tend always to persist and return until the whole physical nature is changed by the transformation of the most material consciousness; till then their pressure recurs — sometimes with a revival of their force, sometimes more dully — as a mechanical habit. Take from them all life-force by refusing any mental or vital assent; then the mechanical habit will become powerless to influence the thoughts and acts and will finally cease.
