Temple of Tooth (of Buddha), Kandy, Sri lanka
The Sacred Relic of the Tooth of the Buddha is venerated in Sri Lanka as a relic of the founder of Buddhism.
According to Sri Lankan legends, when the Buddha died, his body was cremated in a sandalwood pyre at Kusinara in India and his left canine tooth was retrieved from the funeral pyre by Arahat Khema. Khema then gave it to King Brahmadatte for veneration. It became a royal possession in Brahmadatte’s country and was kept in the city of Dantapuri (present day Puri in Orissa).
According to legend, a princess named Hemamali and her husband secretly transported the relic in her hair from India to Sri Lanka. Finally, it was brought to Kandy where it is at present, in the Sri Dalada Maligawa temple. Read more from Wikipedia below.
