in parthiban kanavu it is said that it took 6 years for narasimmar to return to homeland after the battle at vadhabi. in sivagamiyin sabatham it is show that he returned within 1 year. which is right? because neither sivagami nor vanama devi survived for 6 years after the vadhabi battle, to see narasimmar arriving back.but both of them survived when he arrived. so somethin did not tally. can anyone help me?
