A rock and trees near it bearing abundant fruit, Pothgul Vihara area, Rathnapura, Sri Lanka.

A Jak and a coconut tree near a large rock.

The large rock.

The Jak tree bearing a lot of fruits.

It is part of village lore in Sri Lanka that any sap-bearing tree ('Kiri gas') with its roos near a large rock on the ground bear plenty of fruits. They ascribe it to the heat retained by the large rock. I saw this on the road to 'Pothgul Vihara'.
