Sri Dalada Maligawa or the Temple of the Sacred Tooth Relic is a Buddhist temple in the city of Kandy, Sri Lanka. It is located in the royal palace complex of the former Kingdom of Kandy, which houses the relic of the tooth of the Buddha. Since ancient times, the relic has played an important role in local politics because it is believed that whoever holds the relic holds the governance of the country. Kandy was the last capital of the Sri Lankan kings and is a World Heritage Site mainly due to the temple.
Bhikkhus of the two chapters of Malwatte and Asgiriya conduct daily worship in the inner chamber of the temple. Rituals are performed three times daily: at dawn, at noon and in the evenings. On Wednesdays there is a symbolic bathing of the relic with an herbal preparation made from scented water and fragrant flowers called Nanumura Mangallaya. This holy water is believed to contain healing powers and is distributed among those present.
The temple sustained damage from bombings by the Liberation Tigers of Tamil Eelam in 1998 but was fully restored each time.
According to the guide, the tooth is stored in a case (or a like) with 7 locks, which then comes in 7 keys, which are held by different monks located at different places. They will meet once a year or as and when required to unlock to take the tooth out for prayer etc.
The place is really large with many exhibits, we covered all, except the international Buddhist exhibition, which mainly to showcase the Buddhist communities in many countries, including Malaysia.
There is no shoe allowed in the premise, so for tourists, since we are paying 1500LKR (RM37.50), so we got to enjoy a shoe locker service (actually more of someone to store the shoes inside a plastic box, stacking, so kind of dirty).
It is an easy and moderate walk inside the premise. Just need to lower the noise as well as not to photograph some areas.
For Buddists, this would be like a place to visit, and medicate, as I have seen many doing that.
