Why does the bond between brother and sister matter so much for the family?
A sister knows her brother's wellbeing matters
A sister who comes to tie rakhi (a protective thread) is not merely coming to celebrate a festival. She knows that if her brother is well, her parents' old age will go well.
She knows that if my brother is well, my parents' old age will pass well; if he is prosperous and strong, all will be good.
