The remark came when asked by reporters whether he was feeling upbeat after completion of nine years in office and four years of UPA-II.
Singh was quoting a couplet of noted Urdu poet Allama Iqbal which, in full, runs: 'Sitaron Se Aage Jahaan Aur Bhi Hain, Abhi Ishq Ke Imtihan Aur Bhi Hain.'
It means 'beyond the stars, there are even more worlds; there are still even more tests of passion'.
His remarks were significant as sometime back he had not ruled out a third term as Prime Minister.
