Every person is within moksha. Man’s real self and real goal is Moksha itself. But due to impurities of mind he is deluded that he is far away from moksha. Only the body consciousness and selfishness are distancing a person from his self. Due to misdeeds and misconceptions man is not able to experience the eternal bliss. The Eternal bliss that moksha brings is as pure as the Ganges from heaven (akasa Ganga) it has no impurities.
Nirvana is another name for moksha. It implies going beyond body consciousness.
