Mbh 3.292.2b

Narada said, ‘In bestowal of gifts according to his power, the mighty son of Dyumatsena is like unto Sankriti’s son Rantideva. In truthfulness of speech and devotion unto Brahmanas, he is like Sivi, the son of Usinara. And he is magnanimous like Yayati, and beautiful like the Moon. And in beauty of person he is like either of the twin Aswins. And with senses under control, he is meek, and brave, and truthful! And with passion in subjection he is devoted to his friends, and free from malice and modest and patient. Indeed, briefly speaking, they that are possessed of great ascetic merit and are of exalted character say that he is always correct in his conduct and that honour is firmly seated on his brow.’ Hearing this, Aswapati said, ‘O reverend sage, thou tellest me that he is possessed of every virtue! Do thou now tell me his defects if, indeed, he hath any!’ Narada then said, ‘He hath one only defect that hath overwhelmed all his virtues. That defect is incapable of being conquered by even the greatest efforts. He hath only one defect, and no other. Within a year from this day, Satyavan, endued with a short life will cast off his body!’ Hearing these words of the sage, the king said, ‘Come, O Savitri, go thou and choose another for thy lord, O beautiful damsel! That one great defect (in this youth) existeth, covering all his merits. The illustrious Narada honoured by even the gods, sayeth, that Satyavan will have to cast off his body within a year, his days being numbered!’ At these words of her father, Savitri said, ‘The death can fall but once; a daughter can be given away but one; and once only can a person say, I give away! These three things can take place only once. Indeed, with a life short or long, possessed of virtues or bereft of them, I have, for once, selected my husband. Twice I shall not select. Having first settled a thing mentally, it is expressed in words, and then it is carried out into practice. Of this my mind is an example!’
