A "kahuna" is a Hawaiian term that traditionally refers to a person who is an expert or master in a specific field, such as healing, fishing, or building. In Hawaiian culture, kahunas are respected for their knowledge and skills, often serving as spiritual leaders or practitioners of ancient traditions. In modern contexts, the term is sometimes used more broadly to describe someone who is highly skilled or influential in any area, not just in Hawaiian culture. The concept emphasizes the importance of expertise and respect for those who have dedicated their lives to mastering their craft, similar to a guru or mentor.
