The word 自然 is a combination of two kanji: 自 (ji), which means "self," and 然 (zen), which means "so," "like that," or "sort of." The combination of these two characters suggests something that is itself, that is in its own state, hence meaning something that is "natural." The concept likely originated from Buddhist philosophy and Chinese classical texts.
