Important note: These phrases are translations of English concepts, and there might not be a direct equivalent in Hawaiian. The emphasis in Hawaiian prayer is often on connection with the natural world and the spirits within it.
It's also worth remembering that the Hawaiian culture has a deep respect for nature and the elements. When praying for sunshine, it's important to express gratitude for the beauty and power of the sun, while also recognizing that it plays a vital role in the balance of nature.
