A great depiction of the state of mind of parents seeing the sibling grow ...From complete dependence, To total independence..... And allowing the cycle roll on.......which is their own making...
" With the hearts full and empty." "Full" seeing the success of their siblings. "Empty"
This is what is called the state of " unconditional sacrifice"....knowing pretty well that the love of the sibling shall no more be 100% theirs and it is going to be divided between the parents and the new life partner....still they happily plan and celebrate the transition....accepting the situation of "Divided love of children - " ...just to keep the cycle of life on...... " The cycle goes on, On and on"... So did our parents and so we have to do...
