ʻAʻole ʻo wau wale nō ka mea i komo i ka manaʻo.
Eia kekahi, no ka wā e hiki mai ana, makemake wau e mālama, ʻo ka mea mua, noʻu iho, nā hanana hoihoi i kū mai i ka wā o ka hoʻokō. ʻO ka noʻonoʻo ʻana i kēia manawa ua hoʻoholo ʻia kahi hoʻoholo hoʻolālā e hoʻololi i ka hoʻolālā a hoʻololi i ka loiloi ʻoihana i ka pae hope. No laila, ʻaʻohe mea e pono ai nā mea a pau i kūkulu ʻia a lilo i mea hoihoi ʻole i kekahi.
ʻO nā ʻano i wehewehe ʻia ʻaʻole ia he ʻano ʻike a ʻokoʻa paha. ʻike i keʻano, He mea maʻamau nā mea a pau a ua hoʻokōʻia i nā manawa he nui (no ka laʻana, ua hoʻohana au i kahi ala like 20 makahiki aku nei ma Oracle) Ua hoʻoholo wale wau e hōʻiliʻili i nā mea a pau ma kahi hoʻokahi. Ina he mea pono no kekahi. E like me ka hoʻomaʻamaʻa ʻana, hiki pinepine ka manaʻo like i nā poʻe like ʻole. A he mea pono e mālama iā ʻoe iho i mea hoʻomanaʻo.
ʻOiaʻiʻo, ʻaʻohe mea o kēia ao i kūpono, ʻaʻole hiki ke hewa a me nā typos. Hoʻokipa maikaʻi ʻia nā ʻōlelo hoʻohewa a me nā manaʻo. Eia nō naʻe, hoʻohana mau ʻia nā mea a pau i kahi papahana hana maoli. No laila, he sketch wale nō ka ʻatikala a me ka wehewehe ʻana i ka manaʻo maʻamau, ʻaʻohe mea ʻē aʻe.

ʻO ka manaʻo maʻamau ʻo "māhele a lanakila, hūnā a ponoʻī"
ʻO ka manaʻo maʻamau - he papahana kaʻawale no nā papaʻaina, he papahana kaʻawale no nā hana mālama.
