about japa

what is japa?. many do japa, but do not know what it is.its said that" jakaro janma vichheda, pakaro papa nashanaha." the letter ja indicates in sanskrit janma. one who is born.which  means death is also certain.which is a common knowledge. therefore we are in the in the cycle of births and deaths. but do we have  a hope from this samsara. shasthra says "janma vichedaha. cut this bond of janana marana(births and deaths) through removing ur sinful actions(papa nashanaha) we cannot say confidently say i  am not doing papa. when even during a japa, if i kill a mosquito withot my knowledge, thru reflex actions i have to undergo karma phala. everybody has to own up ones own  karmapala. mother 'fater'wife'husband cannot own up ones own karma. here shasthra says u pray and repeat lord's names. first its mecanical, later when i repeat lord's name remains in  my subconscius mind. and it comes naturally. when i am immersed in japa, my evil thoughts also dies away gradually. till it disappears totally, over a period of time.although many peoplle think japa is only repeatition of lords name. but not so.. it really evolves u in searching of supreme reality.
