In the purification of the physical nature, more even than in the rest, it is not safe to assume that there will be no more attacks of old forces or habits of the nature – till the thing is actually and unmistakably done. One must remain vigilant till there is the full siddhi. For in the physical, habit, memory, mechanical response have an immense power of survival – therefore a return of old vibrations or formations is always possible. Only when there is the full purification and transformation is there the perfect security.
