Without which, married life is simply abominable

The purpose of marrying is to beget a son, because a son is necessary to
deliver his father and forefathers from any hellish conditional life in
which they may be. Canakya Pandita therefore says, putra-hinam grham sunyam:
without a son, married life is simply abominable.
