Why does bad things happen to good people?

One may ask , this question and question the judgement of GOD , It often is puzzling when we see some very terrible things happening to people who are good. Well the answer leads to reincarnation.
Reincarnation:
Many people today do not have a slightest of idea about reincarnation or life after death, many people donot "believe" in reincarnation. The question of believing or not believing , arises when one is in ignorance, but when by the grace of Krishna and Guru, one becomes knowlegdable , there is no such thing as belief, everhing is a fact. As per Bhagvat Gita , a living entity after death changes bodies , in the same way as he changes clothes, this phenomena is called transmigration of soul or in other words reincarnation.

The living soul, changes or transmigrate from one body another according to his desires in the past life under the direction of the nature. In that particular body the living soul, does some work during his prescribed lifetime from birth to death and the results of work, that is karma ,has to be paid by the living entity as per the law , so it some of these results are carried to the next life from the previous lives.

Thus , whatever a person experiences ,in this life, i.e good or bad is nothing but the payment of his karma or actions. So a person may be acting good in this life due to his good activities in past life, but , the sinful acts or the bad karma , from the previous lives , puts that particular individual into distress. So happiness and distress experienced by a person are only because of his bad karma and not because of any one else. A person in the current situation who has caused that distress is just a medium by which you are paying off your debt. Now if a person out of ignorace starts blaming others for his distress , he starts developing negative karma, which he has to pay in later stages of life. Thus a person is constantly creating and paying karma in a cycle of birth as per his activities. Now some one may ask , so is there and escape to this cycle , the answer is yes, By sincerely surrendering to the lotus feet of Krishna (GOD) one becomes free from this cycle of birth and death.

Now one more question that may arise is why is that GOD , put us in this viscous circle ,if he is nice?
Well GOD is good, he is always a well wisher of a living entity, It is not GOD's fault that we are stuck in this cycle, but it is our desires which place us in this precarious position. We wanted to lord it over the material nature and become GOD ourselves , and Krishna is just giving us that chance. He never interferes with the little independence we living entities have. In fact , GOD is so kind, that every moment, he finds and the opportunity sitting with every ones heart to instruct the living entity to return back to HIM. He sends his representatives in order to carry out his missions.
