Ananda Thero was the chief personal attendant of living Lord Buddha. He had pure and endless affection and respect towards Lord Buddha. Without any ulterior motives, he dedicated his entire life being the personnel help Lord Buddha.
The sacred left canine tooth relic of Lord Buddha, which is placed in the sacred Temple of Tooth in Kandy, is being blessed with poojas and rituals since it is regarded today as the living Lord Buddha. The personal attendance and traditional services dedicated to Lord Buddha carried out by Ananda thero back then, are being carried on today as Theva (daily services) which are led by the Maha Nayaka Thero of Malwathu and Asgiri Chapters and followed by the residing Maha Sanga of those temples.
Theva are carried out by the Maha Nayaka Thero of MalwathuAsgiri chapters or a Nayaka Thero appointed in charge of theva representing MahaNayakeTheros; these theva are carried out as annual shifts of tenures between Asgiri and Malwathu chapters. Besides the daily services (Theva), there are also weekly and annual poojas and rituals dedicated for the sacred tooth relic which are continuously carried out since ancient times to present.
