“In Thai culture, the head is the most important part of your body, and the feet are considered dirty, cuz that’s on the ground all the time. So it’s very disrespectful if you point your feet at somebody’s head, or if you point your feet at somebody in general. And also, if you step over books, or like, put your feet on books, or put books on the ground, because books are considered knowledge from your head.”
This is a Thai folk belief about knowledge and dirt. The informant says that she learned this belief from her mom when she was a child. She says that she remembers pointing her feet towards the prayer room at Buddha in her house and she remembers her mom reprimanding her for doing so and explaining why it was wrong to do so. It makes sense that the feet are associated with dirt and the head is associated with knowledge, so this is a folk belief that is tied a lot with logic. Furthermore, books are also associated with the brain in Thai culture, because books contain the knowledge that people have in their heads. Therefore, stepping on books, or even stepping over books is considered offensive, as it is considered to be stepping on somebody’s knowledge. This also branches out to temples and houses as well. A person is not allowed to enter a temple or a house with shoes that one would wear in the outside world, because they are entering an area of holiness and family.
This folk belief is also an oicotype of the folk belief in India. In India, people are not allowed to wear their shoes into a temple or a home. Often times, it is even encouraged for people to wash their feet before they enter, to cleanse the dirt that they may have. Both Thai and Indian culture have such a similar folk belief because there was a lot of interaction between the two cultures over the past hundreds, if not thousands of years. It is extremely plausible that many pieces of folklore exchanged between the two countries and developed along in similar fashions.
