The King offered him the royal flower garden (Suan Dok) as a place to build a temple. The temple was established in 1914 A.D.
When Sumana Thera was living in Sukhothai, he had a vision which showed him where to find a very holy relic that had long been buried near the city. When the relic was unearthed, miraculous illuminations took place confirming its power. These miracles did not repeat themselves for the King of Sukhothai, who left the relic in the care of the monk.
