Shakyamuni while in the Causal Stages (of Bodhisattvahood) as a Parrot Performs Filial Acts
The Great Canon states: There was a parrot whose father and mother were completely blind and who always when gathering flowers and fruit first offered them to his parents. At this time there was a landowner, who when he began to plant his grain, made a pledge, “Whatever crop I plant, I will give to the myriad creatures in charitable offering.” The parrot was then gathering rice grains in order to nourish his parents. At the same time, the landowner saw the parrot and suddenly got angry, and seized the parrot. The parrot informed him, “First (you) had a good heart, granting creatures (nourishment) without being stingy; why is it that today upon seeing me (you) seize me?” The landowner asked, “You are here gathering my grain, how did you expect me to react?” The parrot replied, “My parents are blind; I desire to offer this to them.” The landowner was delighted (to hear this), and thereupon let him go.
At that time the World-Honored One spoke this hymn: How excellent! The parrot had wisdom, thus could he cherish and filially care for his parents. I henceforward will supply gifts of seeds to allow you to provide for your two parents. Such unlimited events in the past were like this. Always cherishing that which was abhorrent, thereby seeking pure and peerless enlightenment.
