In particular, Sanskrit characters representing the guardian deities of the Chinese zodiac are said to protect against the misfortunes of one's zodiac sign and lead to good fortune, and are worn as amulets. Furthermore, since Sanskrit characters represent the "energy and existence of gods and Buddhas" themselves, they are believed to possess sacred power and function as amulets to guide the owner's life in a better direction. ※ The main stone words for smoky quartz are "stability," "healing," "sense of responsibility," "good sleep," and "honesty."
