For every trouble which comes upon a man, it is fitting that he should pay attention and check his deeds, for Hashem has done this so that they will fear from him, and He sends a trouble to a person so that he will pay attention to arouse himself to repent. If, on a day when he is troubled he does not arouse himself to repent and just assumes that the trouble came about by coincidence, his punishment is explicit in the Torah as it says “And if with these you will not be punished by me and you go coincidentally with me; and I will also go coincidentally with you and I will continue to give you trials and tribulations!”. It follows that a person should be careful that when he is having trouble, he should accept upon himself to repent from a particular sin which he has committed, and with this he will merit that that particular trouble will be removed from him.
