It may seem strange to find monks rummaging. Bear in mind that many of the genuine amulets have 'ancestry' based upon monks and temples.
The world over, people seek out lucky charms - amulets - with which to either safeguard their own destiny, or to bring them just that little bit of good luck and fortune that will make life just that little bit easier - or maybe more bearable. Thailand is no different. In fact, Amulets are an important part of Thai life - culture even - and there is a huge market devoted to just that. The sale and provision of Amulets. Where there is a demand, there will be a supply. If the size of the supply is an indication, then there is a huge demand for Amulets in Thailand - certainly in Bangkok.
