"Vaisampayana continued, 'Mention being made of the great Rishi, Bhishma with joined palms said, 'That man is truly intelligent who fixes his eyes judiciously on virtue, profit, and pleasure, and who after reflecting with patience, acteth in such a way that virtue may lead to future virtue, profit to future profit and pleasure to future pleasure. Therefore, that which hath been said by thee and which, besides being beneficial to us, is consistent with virtue, is certainly the best advice and hath my full approval.' And when Bhishma had said this, O thou of Kuru's race, Kali (Satyavati) thought of the Muni Dwaipayana and Dwaipayana who was then engaged in interpreting the Vedas, learning that he was being called up by his mother, came instantly unto her without anybody's knowing it.
