Kathasaritsagara 1.2.4

Then Pushpadanta wandering on the earth in the form of a man, was known by the name of Vararuchi and Katyayana. Having attained perfection in the sciences, and having served Nanda as minister, being wearied out he went once on a time to visit the shrine of Durga. And that goddess, being pleased with his austerities, ordered him in a dream to repair to the wilds of the Vindhya to behold Kanabhuti. And as he wandered about there in a waterless and savage vood,|| full of tigers and apes, he beheld a lofty Nyagrodha tree. And near it he saw, surrounded by hundreds of Pisachas, that Pisacha Kanabhuti, in stature like a Sala tree. When Kanabhuti bad seen him and respectfully clasped his feet, Katyayani. sitting down immediately spake to him. "Thou art an observer of the good custom, how hast thou come into this state?" Having heard this Kanabhuti said to Katyayana, who bad shewn affection towards him, I know not of myself, but listen to what I beard from Siva at Ujjayini in the place where corpses are burnt; I proceed to tell it thee. The adorable god was asked by Durga—"Whence, my lord, comes thy delight in skulls and burning-places?" He thereupon gave this answer.
