historical tree in the world, which is well maintained states: Later life Sangamitta died at 203 BC at the age of 79 in the ninth year of the reign of King Uttiya at her residence in Hatthaloka Upasikaramaya Anuradhapura. Uttiya performed her last rites. The occasion was also marked with observances in her honour throughout Sri Lanka, for one week. She was cremated to the east of the Thūpārāma near the Cittasālā, in front of the Bodhi-Tree. The location for the cremation had been selected by the Therī herself before her death. A stupa was erected by Uttiya over her ashes. Bhikkhuni Sangha The Bhikkhuni Sangha (a Dhamma-vinaya heritage started by Buddha during his lifetime in India), locally known as Bikhhuni Sasana or Meheini Sasna (Order of Priestesses or Nuns) that was established by Sangamitta in Sri Lanka prospered for over 1000 years, till it disappeared in 1017 AD. The reason for such an end is attributed to the invasion of Cholas, Hindu rulers from South India, whereafter Bhikkhus and Bhikkunis were not seen in Sri Lanka for quite some years. Bhikkuni ordination is the third and ultimate stage of ordination of nuns; the earlier two stages are the sramanerika (novice) and siksamana (probationary). In India, the Bhikkuni Order was established by Buddha six years after the Bhikkhu Order was established, in the 6th century BC. It was spread to Sri Lanka by Sangamitta in the 3rd BC. Initially, with spread of Buddhism in ancient India, 18 (eighteen) Vinaya schools developed. However, now only three are extant. These are the Theravada practiced in Sri Lanka and Southeast Asia; the Dharmaguptaka that is practiced in Taiwan, China, Korea, Vietnam and the Philippines; and the third school is the Mulasarvastivada adopted in Tibet. In 429 AD, Bhikkuni Devasara had realised that Bhikkuni Sanga, on account of war and famine, could vanish from Sri Lanka. She, therefore, had led a mission to China to establish the Bhikkuni Sasana. The original Theravada Bhikkuni lineage established in China since 429 AD has continued to function to this day. However, Asarana Sarana Saranankara Maha Thera re-introduced the Higher Ordination from Thailand. He is credited with re-establishing the Order of Monks in Sri Lanka in 1753 AD. It is now said that there are more than 400 Bhikkunis in the country. In Thailand, the lineage is well established. A clay statue of Sanghamitta made by Dhammananda in
