‘Japa’, is made of two letters, ‘ja’ and ‘pa’,
‘Jakaro janma vischeda: pakara: papanashanam’;
‘ja’ stands for liberation or moksha and ‘pa’ stands for obliteration of all sins.
Thus, Japa atonce removes our sins and makes us free from janmas (cyle of births and deaths).
जकारो जन्मविच्छेदः पकार पापनाशकः
