Makha Bucha is one of the four most important Theravada Buddhist holidays in Thailand. More than a thousand monks and hundreds of thousand devotees were gathering at Dhammakaya Temple in Thailand's capital Bangkok to attend the lighting ceremony on Thursday. /VCG Photo

Makha Bucha commemorates the full moon day of the 3rd lunar month when Buddha delivered his core teachings. The teachings were called Ovada Patimokkha, which summarized as “cease from all evil, do good deeds and cleanse monks’ mind.” /VCG Photo
