Did you mean Lohi'au, a young chief of ancient Hawai'i who was slain by Pele the volcano goddess, or lo'i, the wetland patches of taro?
If you mean lo'i:
The mental and physical aspect of working in the lo'i is, at least for me, it allows my mind to just "turn off" for a little while and let my body do the work bent over and planting the taro, weeding and removing the apple snails, and when it's ready, harvesting the taro. Of course though it is mentally relaxing, it's physically back-breaking work having to trudge through knee-deep mud, staying bent over for much of the time and sometimes coming across a taro or a weed that just doesn't want to come out.
As for spiritually, in some of the mo'olelo (the oral histories) of the Hawaiian people, the taro plant is our older brother. In a love affair between Wakea (Sky Father) and Ho'ohokulani (Maker of stars in the heavens), Haloa was born, but he was still born so they buried him and where he lay, a taro plant grew. They eventually had another child and named him Haloa also. This is the first Hawaiian that the royalty of Hawai'i trace their genealogies back to, well actually we trace it back to Wakea, but Haloa was the first mortal man.
Maybe a reason Hawaiians saw the taro as being human-like is that when it's cut, it "bleeds" a red sap with the texture of human blood. When it dries, it turns a dark brown color just as human blood does. As far as I know, this was the only plant known to the ancient Hawaiians that did this.
