Roshi is a title used in Zen Buddhism to refer to a master or teacher who has attained a high level of spiritual insight and understanding. The term is often associated with those who guide students in meditation and the practice of Zen, helping them to deepen their experience and understanding of the teachings of Buddhism. In popular culture, the term "Roshi" is also known from the character Master Roshi in the Dragon Ball series. He is depicted as a wise and powerful martial arts master, often providing guidance and training to the main characters. This character has contributed to the broader recognition of the term outside of its religious context.
