Adverse periods in one's life can trigger problems, but these problems do not necessarily get solved at the end of such period. The solution is dependent on the action taken.
A person may get cancer when he is running the period of a malefic as per his horoscope. It's a trigger. But, he is not naturally cured of it at the end of such period. The cure depends on treatment given and divine blessings etc.It is not correct to believe that problems will get solved by themselves at the end of adverse periods. Problems get solved on the basis of action taken. Of course, circumstances turn favorable when good period comes, but that alone need not bring in a solution.
Don't wait under the hope that once the bad period goes everything will be fine. It may not happen. Once infected, an antibiotic is required for cure.
