A famous stone image in Anurādhapura, evidently held in great reverence. It was originally in the Abhayuttara vihāra, and Buddhadāsa placed a Nāga-gem as one of its eyes (Cv.xxxvii.123); but this was lost, and then Dhātusena had a pair of costly eyes made (Cv.xxxviii.62).
It was referred to under various names: Silāsatthā, Silāmayamuninda, Kālasela-satthā, etc. Sena II. found the temple containing the image in ruins and had it repaired (Cv.li.77), while his queen Sanghā placed on the image a dark blue diadem (Cv.li.87).
