ʻO ka helu 1 he helu prime, e like me ka manaʻo o kekahi poʻe kālailai i ke kānāwai o nā helu prime. Hana ʻia ka helu prime i ka helu ʻoi aʻe ma 1, a he nui nā kālele ʻole aʻe i ka 1 a me ka helu iho. No ka mea, hiki i ka helu 1 ke hoʻokaʻawale ʻia e ka 1 a me kona iho, manaʻo kekahi e like me ia i nā kūlana o ka hoʻolālā ʻana i ka helu prime. ʻO kekahi poʻe kālailai, manaʻo lākou e hāʻawi ana i ka helu 1 i ka helu prime i mea e hoʻoponopono ai i nā ʻōlelo piha no ka ʻimi ʻana i nā kumu no nā helu prime a me nā hana i ka helu e pili ana. Hoʻokahi kumu o kēia manaʻo, e hoʻōla ana i ke kumu hoʻonohonoho ʻana ma o ka hoʻohālikelike ʻana i ka ʻIke paʻa i nā helu a me nā lōʻihi.

Ma nā ʻano like ʻole o ka wā ma mua, ʻaʻole paʻa ʻākea ka manaʻo o nā helu prime, a i kekahi manawa, komo ka helu 1 i ka helu prime ma kā nā kālailai kūloko ma mua. ʻO ka poʻe kālailai i kēia manaʻo, manaʻo lākou he hana nui ka helu 1 i ka hoʻolālā ʻana i nā ʻōlelo piha ma nā helu ʻoiaʻiʻo. Hōʻano lākou e ʻike ana i ka 1 e like me kahi helu ma ka hoʻonui ʻana i nā manaʻo piha i nā helu prime, e hōʻano ana i ka hāʻawiʻana i nā helu o nā ʻōlelo i ʻike kaʻa. I ʻole o kēia manaʻo, ma kēia manawa he nui nā kānāwai i nā helu prime e hoʻoponopono ai i ka hana i ka ʻike i nā manaʻo ma kekahiʻoiaʻiʻo.
