Mbh 12.117.1b

Indeed he came to that very hermitage for the object of slaying the Rishi's lion. Seeing this, the sage transformed his lion into a Sarabha of great strength. The wild Sarabha, beholding the Rishi's Sarabha before him to be fiercer and more powerful, quickly fled away, from that forest. Having been thus transformed into a Sarabha by the sage, the animal lived happily by the side of his transformer. All the animals then that dwelt in the vicinity became inspired with the fear of that Sarabha. Their fear and the desire of saving their lives led them all to fly away from that forest. Filled with delight, the Sarabha continued every day to slay animals for his food. Transformed into a carnivorous beast, he no longer affected fruit and roots upon which he had formerly lived. One day that ungrateful beast who had first been a dog but who was now transformed into a Sarabha, eagerly thirsting for blood, wished to slay the sage. The latter, by ascetic power, saw it all by his spiritual knowledge. Possessed of great wisdom, the sage, having ascertained the intentions of the beast, addressed him in these words.
