Iraivan will poke your eyes
They used to say Iraivan will poke your eyes if you do bad. Is Iraivan someone walking around with a needle and waiting to poke everyone's eyes?
Iraivan is full of kindness and love, doesn't know to punish.
It is what we do that comes back to us
Once a man called a passerby. He told him this "I am going to get a mail today", the passerby man was wondering whether it is true. Then a postman came and gave a letter to this man, the passerby got shocked and asked him how he knew that. The man replied that he only posted the mail to himself.
So in a similar way, whether it is Good or Bad, it is what we do that comes back to us.
Our ancestor's loan
Once a man went to a hotel. He ate a small meal. The bearer came and gave a huge bill. This man was shocked to see this bill, he then asked the bearer why so much cost for just a small meal. The bearer said that they charge for the food that was eaten by his grandfather and great-grandfather too.
In the same way, we get the fruits of our ancestors.
Note: here Iraivan means God in Tamil
