Buddhism is on the decline in Thailand, with the onset of economic prosperity . The signs are there.In olden times, there was hardly any shopping mall in any area. There were few cars, let alone flashy ones. There were fewer forms of modern-day sophisticated entertainment. Life in a village revolved around the wat. The monk was a respected figure, a figure of authority, someone you would seek counselling and advice from. Not anymore. Now, there are shopping malls everywhere, which are usually packed with people. Highways are filled with fast-moving cars, including fancy ones.
The age of materialism and consumerism has set in. It has pervaded even religion. "Thais are embracing consumerism with gusto!" Now 'spiritual materialism' expresses itself in the 'buying of good karma' with donations! The core value of selflessness is being replaced by - "bigger is better", "the more you give the more you get"! "I buy ,therefore I am". One is now "identifying one's life with what one owns".(Professor Butt)
Less and less people are interested to become monks, even to become novice monks for a short period of time(which, until recently, was popular among young Thais). One reason for this is that, as a result of family planning, Thai families now have fewer sons, sometimes only one. Hence, parents are reluctant for their "only son" to become monks. They'd rather they study and pursue a suitable career and raise a family.
However, deep at the heart of all this, is that times have changed. Buddhism may not have been relegated to a museum yet, but today's world requires a more thinking and critical/analytical approach to Buddhism as a religion. Also, meditation, including insight meditation,has now become a necessary part of practice.Finally, as Severson puts it, Thai Buddhism "needs new packaging".
