"Trust not in those," etc. This story the Master told in the Bamboo Grove, on the subject of going about to kill. In the Hall of Truth, the Brethren were discussing the evil nature of Devadatta. "Why, Sir, by suborning archers and others to the task, Devadatta is making an attempt to murder the Dasabala!"  The Master, entering, enquired, "What is this, Brethren, that ye speak of
as ye sit here together?" They told him. Said he, "’Tis not now the first time that he has tried to murder me, but it was the same before" ; and he told them a story of the past.
Once upon a time there reigned in Kosambī 1 a king named Kosambaka. At that time the Bodhisatta became the offspring of a wild hen that dwelt in a grove of bamboo trees, and afterwards was the chief of a flock of several hundred fowls in the forest. Not far off lived a Falcon, which as he found opportunity caught the fowls one by one and ate them, and in course of time he devoured all the others, and the Bodhisatta was left alone. But he used all caution in seeking his food, and dwelt in a thicket of bamboo. Here the Falcon could not get at him, so he set about thinking by what trick he might entice him to capture.
Then he alighted on a branch hard by, and called out, "Worthy Fowl, what makes you fear me? I am anxious to make friends with you. Now in such a place (naming it) is food in plenty; let us feed there together, and live like friends in company."—"No, good Sir," replied the Bodhisatta, "betwixt you and me no friendship can ever be; so begone!"—"Good Sir, for my former sins you cannot trust me now; but I promise that I will never do so again!"—"No, I care not for such a friend; begone, I say!" Again for the third time the Bodhisatta refused: "With a creature of such qualities," quoth he, "friendship there must never be"; and he made the wide woods resound, the deities applauding as he uttered this discourse:
"Some men have nature like the kine, thirsty and full of greed: "These hold out dry and empty hands; the voice conceals their heart;  "Put not thy trust in woman or in man of fickle mind, "The man who walks in evil ways, to all things threatening death, "Some speak smooth words that come not from the heart, and try to please "When such an evil-minded man beholds or food or gain,
Self-interest, nor who have sinned, nor who too-pious show.
Have words in truth a friend to soothe, but never come to deed.
From those who know not gratitude (vain creatures!) keep apart.
Nor such as having made a pact to break it are inclined.
Unstedfast, put no trust in him, like keenest sword in sheath.
With many a show of friendship feigned: put not thy trust in these.
He works all ill, and go he will, but first will be thy bane."
"Some men have nature like the kine, thirsty and full of greed:
"These hold out dry and empty hands; the voice conceals their heart;
 "Put not thy trust in woman or in man of fickle mind,
"The man who walks in evil ways, to all things threatening death,
"Some speak smooth words that come not from the heart, and try to please
"When such an evil-minded man beholds or food or gain,
 These seven stanzas were repeated by the King of the Fowls. Then were the four stanzas following recited by the King of the Faith, words inspired by a Buddha's insight:
"Who is not quick to recognise the meaning of events, "Whoso the meaning of events is quick to recognise, "From such inevitable and treacherous snare,
As the Fowl left the Falcon, so ’twere best bad men to leave.
Under his foes' control he goes, and afterward repents.
As from the Falcon's toils the Fowl, so from his foes he flies.
Deadly, set deep mid many a forest tree,
As from the Falcon far the Fowl did flee,
The man of seeing eye afar should fare."
"Who is not quick to recognise the meaning of events,
"Whoso the meaning of events is quick to recognise,
"From such inevitable and treacherous snare,
And he again, after reciting these stanzas, called the Falcon, and reproached him, saying, "If you continue to live in this place, I shall know what to do." The Falcon flew away thence and went to another place.
 The Master, having ended this. discourse, said, "Brethren, long ago as now Devadatta tried to compass my destruction," and then he identified the Birth: "At that time, Devadatta was the Falcon, and I was myself the Fowl."
