What is that? Sorry but I'm not familiar with Thai terms.
But if it's some kind of amulets, it is definitely not of orthodox
Buddhist origins but of Thai/Brahmanistic origins.
Native Thai (to be exact, through the Brahmanism influence) has a
culture of amulets and even dealing with spirits. This is something
that Thai Buddhists should not focus too much on, but instead on
his practise of dhamma & liberation.
