Ajinkya Kamble

in season 5 episode 77 all the asuras which were killed by shri krishna attained moksha or mukti, which means liberation from life and death and mix in parmatama, but in that episode all the asuras were again recollected in patal loka when shri balram was trapped by shukracharya. This means that after attaing mukti one can again come to life? please stop this or change the sense. other everything is fantastic. thanks
