Mbh 3.75.1a

“Vrihadaswa said, ‘Hearing everything, Damayanti became oppressed with grief, and suspecting the person to be Nala, said unto Kesini, ‘O Kesini, go thou again, and examine Vahuka, and staying in silence at his side mark thou his conduct. And, O beauteous one, whenever he happens to do anything skilful, do thou observe well his act while accomplishing it. And, O Kesini, whenever he may ask water or fire, with the view of offering him obstruction, thou shalt be in no hurry to give it. And marking everything about his behaviour, come thou and tell me. And whatever human or super-human thou seest in Vahuka, together with anything else, should all be reported unto me.’ And thus addressed by Damayanti, Kesini went away, and having marked the conduct of that person versed in horse-lore, she came back. And she related unto Damayanti all that had happened, indeed, everything of human and superhuman that she had witnessed in Vahuka. And Kesini said, ‘O Damayanti, a person of such control over the elements I have never before seen or heard of. Whenever he cometh to low passage, he never stoopeth down, but seeing him, the passage itself groweth in height so that he may pass through it easily. And at his approach, impassable narrow holes open wide. King Bhima had sent various kinds of meat--of diverse animals, for Rituparna’s food. And many vessels had been placed there for washing the meat. And as he looked upon them, those vessels became filled (with water). And having washed the meat, as he set himself to cook, he took up a handful of grass and held it in the sun, when fire blazed up all on a sudden. Beholding this marvel, I have come hither amazed. Further, I have witnessed in him another great wonder. O beauteous one, he touched fire and was not burnt. And at his will, water falling floweth in a stream. And, I have witnessed another greater wonder still. He took up some flowers, began to press them slowly with his hands.
