King Dwaniatisa

  

It seems there might be a slight misunderstanding with the name "King Dwaniatisa." Based on historical records, there is no prominent Sri Lankan king by that exact name. However, it's possible that you may be referring to **King Devanampiyatissa**, who was an influential ruler in Sri Lankan history. He is renowned for being the first Sinhalese king to embrace Buddhism after the arrival of the teachings from India, thanks to the missionary work of Arahat Mahinda, who was sent by Emperor Ashoka of India.

If you meant a different king or a historical figure with a similar name, could you please provide more context or clarify the name? That way, I can provide you with a more accurate response.
