Something that's heavenly or otherworldly is supernal. A supernal understanding of life, for example, would be a deeper, spiritual, or religious awareness.
Things with a spiritual emphasis can be described as supernal, particularly in books and religious literature. A religious Christian might find supernal wisdom in the Bible, while supernal revelations might come to a Hindu during prayer in a temple. Supernal can also mean simply "exceptional:" "The supernal poets are the ones who put words to feelings." The Latin root is supernus, "situated above."
