The Sri Lankan Bhikuni Order, founded and developed by the Buddhist nuns of Saṅghmittā around the 3rd century BC, were annihilated by the famine and invasion of the Chola tribes of South India around the 11th century. About 1,000 years later, in 1996, the Sri Lankan ‘Bhikuni Dharma-lineage was restored’ by Korean Buddhism. Although Korean Buddhism has accomplished such great historical achievements, there are few basic records of this important event due to internal Buddhist issues. Since little is known about the history of this precept ceremony, such as witnessing acarya and others traces. Scholars from various countries studying the problem of the Bhikuni Dharma-lineage in Southern Buddhism have inquired of the author several times because I have written one or two papers in this field. But I could not answer the questions because I did not understand the Ceremony Construction they asked. So, I started to record the basics of the ceremony, such as finding and recording the history of the elder monks who participated in the ceremony. In the process, it was possible to obtain the Ceremony Construction table prepared at the time of the precept ceremony. Accordingly I was able to write this thesis based on that table. Even now, 25 years later, it is quite fortunate to be able to record the noble achievements of the Sri Lankan ‘Bhikuni in their efforts to restore the Dharma-lineage.
