An Elder of Ceylon. He once went to Jambudípa, embarking at Mahátittha in a boat, in which he dwelt in seclusion. On the way across, while looking at the ocean, he developed ápokasina (Vsm.170).
Another thera of the same name is mentioned in the Commentaries and is described as a Samyuttabhánaka. It is said that because he dwelt in mettá poison had no effect on him (Vsm.313; AA.i.865). He probably lived in the time of the Bráhmanatissabhaya (q.v.). His colleagues were Isidatta and Mahásona. During the time of the peril, he took leave of his colleagues and went to worship at the Mahávihára. He found it empty and started for the south, when the sprite of a neighbouring tree, assuming human form, looked after him and escorted him to a village near the Jajjaranadí, where he was supported by foresters (?pannakhádakamanussá) till the peril was past (VibhA.446). The Digha Commentary (DA.iii.883) mentions another Cúla-Síva and calls him Tilokanagaravási (v.l. Lokuttaravásí). He was evidently a well-known commentator.
