Ok I know it's a show but they do say art imitates life.
Why would the writers give a good person so much suffering? I could not understand why so much bad things happen to good people? Why Sawri's birth right should be given away? Why torment Saloni for 11 years? The woman prayed and lived a pious life; Yes I am aware the writers are joyless individuals.
My answer is to forget there is a show called SP. But then I started to wonder what about reality? Why do bad things happen to good people? Why do good things happen to bad people? Why did the identity of Saloni's daughter fall into Jiji's hands? Maybe there is no answer except bad writing on the part of the SP writers.
So I started to think it's an Indian Serial so it must be based on ideologies and scriptures from India. So I did some research and came up with Reincarnation and Karma.
The belief in rebirth and various realms is a common ideology in Hinduism. According to Hinduism a soul is reincarnated again and again, undergoing many experiences, until it achieves perfection and unites as one with the divine. This idea of rebirth is referred to as reincarnation, that death relates only to the physical body but the soul continues on and is reborn into another body, human, animal or sometimes even a vegetable.
Karma" refers to the "debt" a soul accumulates because of good or bad actions committed during one's life (or past lives). If one accumulates good karma by performing good actions, he or she will be reincarnated in a desirable state. If one accumulates bad karma, he or she will be reincarnated in a less desirable state.
Reincarnation could explain why bad things happen to good people and why good things happen to bad people: they are being rewarded or punished for actions in past lives (karma).
Consider the story of the Chinese farmer whose horse ran off. A friend commented on how unlucky this was. The farmer replied, "maybe good, maybe bad, who's to say?" The next day the horse returned leading a herd of wild horses that went right into the corral. The same friend as before commented on the farmer's good luck. Once again the farmer replied, "maybe good, maybe bad, who's to say?" The next day the farmer's son was riding one of the wild horses to tame it. He was thrown off and broke his leg. The well meaning friend told the farmer, "you have lost the services of your son and he is in such pain. I am so sorry for your bad luck." Undaunted, the farmer once again replied, "maybe good, maybe bad, who's to say?" The next day, the Chinese army passed through the area recruiting every able-bodied young man to fight a war in a distant land. The moral - "maybe good, maybe bad, who's to say?"
