Koṇāgamana (Pāli), also known as Kanakamuni in Sanskrit or alternatively Koṇāgon or Kanakagamana, is one of the ancient Buddhas whose biography is chronicled in chapter 23[2] of the Buddhavaṃsa, one of the books of the Pali Canon.
Koṇāgamana Buddha was born in Sobhavati, the capital of King Sobha (present day- Nigali Sagar, Nepal) within the serene Subhagavati Park.
Koṇāgamana Buddha spent three thousand years in his royal household, residing in three palaces: Tusita, Santusita, and Santuttha.
The inscription made when Emperor Asoka at Nigali Sagar in 249 BCE records his visit, the enlargement of a stupa dedicated to the Kanakamuni Buddha, and the erection of a pillar: "Devanam piyena piyadasin lajina- chodasavasa bhisitena Budhasa Konakamanasa thube-dutyam vadhite Visativa sabhisitena –cha atana-agacha-mahiyite silathabe-cha usa papite" “His Majesty King Priyadarsin in the 14th year of his reign enlarged for the second time the stupa of the Buddha Kanakamuni and in the 20th year of his reign, having come in person, paid reverence and set up a stone pillar”.
[9][10]According to Xuanzang, Koṇāgamana's relics were held in a stupa in Nigali Sagar, in what is now Kapilvastu District in southern Nepal.
