Fortune telling books that monks us in Thailand called?

In Thailand, fortune-telling books that monks use are called "Tamra Saastras" or "Tamra Phaen Din". These books contain ancient scripts, diagrams, and illustrations that are believed to provide guidance and predictions about various aspects of life, such as health, wealth, career, and relationships. Monks may use these books for divination purposes or to provide guidance to individuals seeking spiritual advice. "Tamra Saastras" are considered sacred and are often passed down from generation to generation within the monastic community.
