"PHI TON MAI" means "ghosts that reside in tree". Everywhere in Thailand, some trees are wrapped with a cloth. Especially in temples but also in forests. It means that a spirit inhabits the tree. Of course the tree shall not be cut without warning the spirit in order to let him find another tree. There is often a certain spirit associated to a certain type of tree such as banana tree spirits and so on.."NANG MAI" is a female spirit inhabiting a tree.

To protect forests against logging, some monks ordain trees and wrapped them up with a thin orange cloth. Trees were then sacred. For Buddhist people it was now impossible to harm the trees.
