Ke Ao Maoli
Aloha,yes the spiritual realm/world/etc. plays a big part and sometimes it can control one in many ways. It is also sometimes hard because when people hear or see one speaking about those before like ancestors,etc.often times they think one is crazy and needs help.
aloha, on your question, I will say what was said in the days of my great great great grandpa Kakuhiewa, "he lani, i luna, he honua, i lalo." This was repeated even in the days of grandpa Lupekapu, king consort to grandma Kalaimanuia and during the days of grandpa "keliimaikai" and each island as told to me when I was little growing up by my kupunas. Everything done in the physical world is observed by the spirit world. God is not one to be mocked. So, we must keep our focus and not be imitating those who by their actions have no respect for kupunas, kahus or even the one who by the divine rights of kings sits on the throne for each answer to the one higher like you read in hemolele babiblia, "the head of the woman is man, the head of the man is Christ and the head of Christ is IO." Children, listen to your parents as our lord listened to his when on the earth for the promise is, "you will live a long long time". So, food, kapa, work and play is a part of the life given with parents who went thru these before you and know what to avoid and who would make a lasting impression on your life and when we are young, we do well when we listen, don't you agree?
