Namaskar,
Yes ,it can be said that itis for the punishment of parents.
But who is the punishment giver

?
As Deepak has said,God does neither reward nor punish.
JV says God never interfere in your life. According to the Jv phylosophy,"you are the architect of your own destiny".That means it says, every reaction has an action in past. This Past may be a previous birth , which nobody remebers .
So instead of saying the punishment got from an unknown , JV says it is their own actions in their past which are responsible for getting such kind of destiny.Same is the case with an infant.He might have done something wrong in his past birth.
To understand this , one should believe in re-birth.Do you believe???
if not,then assume for sometime that there is re-birth (atma is immortal ,also said by Bhagwatgita)
Still your qt remains unanswered , pl continue till you get satisfied.Because this is only a secret of human life ,rather a Gurukilli i.e. Masterkey to happy life taught by Shri Sadguru.This is what an essence of JV knowledge.this is what JV is trying to explain to live life happily.
regards,
Meena
May God bless all
