Being born on May 4, 1959 in Rakhine State in Burma, Ashin Kelasa underwent basic Buddhism studies at Tanlwe-Ywarma Monastery School (TMS) in Taung Gup township. After graduating from the Buddhist High School or Patha-malat in Burmese from TMS, he continued his undergraduate studies at Shew Hinthar Tawya College. In 1979, he received a Bachelor of Dhammā-cariya degree.      

After passing the State High School Examination administered by the Ministry of Education, Burma, he was admitted to the State University of Pariyatti Sāsana (SUPS) in Rangoon in 1986.

Based on his 25 years of meditation experience and knowledge of Buddha teachings, he has been providing medication training and dhamma talks to the communities.
