Catumatta Jātaka (No.187)
Two geese from Cittakūta once used a certain tree
as a perch, whenever they approached it, and became friendly with the spirit of
the tree, who was the Bodhisatta. They talked together about religion until a
jackal came and interrupted them. Then the geese flew away and did not return.
The story was told of an old monk who interrupted a conversation between
Sāriputta and Moggallāna. The monk was the jackal. J. ii.106f.
