Once due to an error in his charitable gift of a cow, prompted by his own sins and crooked intellect, he became a chameleon and was redeemed by Śrīkṛṣṇa.
Pṛṣadhra, a son of Manu was made the keeper of cows by his preceptor. During the nights, observing the posture of heroes, he diligently looked after the cows.
Once a tiger entered the cowshed to attack the cows. On hearing the shrieks of the cows he woke up. Strong that he was he seized a sword to kill it and started.
On seeing the lord armed with a sword the frightened tiger slipped away. Not knowing it and mistaking a reddish brown cow as the tiger he hit it with his sword on its head.
