Thank you ishara_lk,
I visited some Buddha relics while in Myanmar at the beginning of the year inc. the Buddha's colar-bone relic at a monastery at the base of Mandalay Hill, the hair relic at Bautatong Paya and the hair relic buried within Shwedagon Paya. And according to legend, Shwedagon Paya contains relics of the last four Buddhas.
I also saw the relics of many arahants at the main temple on Mandalay Hill.
Thanks again for sharing,
