I'll leave this section for anything on the culture. I'll start off with a few proverbs, known to us as 'Olelo No'eau.
I ulu no ka lälä i ke kumu
The branches grow because of the trunk.
This one reminds us that without our ancestors we would not be here.
He ipu ho'oilina mai nä kupuna mai
An inherited container from the remotest ancestress.
The ipu, which is part of the squash family is dried out and used as a container to hold things, as well as used as an instrument. It compares the ipu to the the womb, the container by which the family line continues.
I pa'a i kona 'a'ole käkou e puka
Had our ancestress died in bearing our grandparent, we would not have come forth.
This one I've heard people use before. And that we should respect the elders because they came first.
I pa'a iä ia 'a'ole 'oe e puka
If it had ended with him [or her] you would not be here.
One of my favorites, which we use to remind the younger generation that respect should be given to the elder. Literally it says how if it was closed (meaning the womb) at the time of the (older) sibling, you (or us, if you're younger) would not be here. I've had this happen in my own family where my great-grandmother died shortly after giving birth. Her daughter, with the same name eventually suffered the same fate. Now had they not died right after childbirth, they probably would have had more children.
All of these 'olelo no'eau I used covers a main aspect of Hawaiian culture and that is having respect. In old days, there was a class system and the ali'i class, or chiefly class was on the top of that tier, followed by the maka'ainana or the common class. Then you had your outcast (kauwa/kauä) at the bottom. But even among the ali'i, you had various classes of chiefs, one higher than the other. All of whom gave respect to whomever was owed that respect based on lineage, rank, title, etc. Even today this is carried, although we did away with the classes, but among the older and younger generations. That doesn't mean that everyone follows it, especially non 'Oiwi or native people.
