Mbh 9.46.17

"I have thus told thee, O king, everything about the installation of Kartikeya. Listen now to the history of the sacredness of that foremost of tirthas on the Sarasvati. That foremost of tirthas, O monarch, after the enemies of the gods had been slain, became a second heaven. The puissant son of Agni gave unto each of the foremost ones among the celestials diverse kinds of dominion and affluence and at last the sovereignty of the three worlds. Even thus, O monarch, was that adorable exterminator of the Daityas installed by the gods as their generalissimo. That other tirtha, O bull of Bharata's race, where in days of yore Varuna the lord of waters had been installed by the celestials, is known by the name of Taijasa. Having bathed in that tirtha and adored Skanda, Rama gave unto the Brahmanas gold and clothes and ornaments and other things. Passing one night there, that slayer of hostile heroes, Madhava, praising that foremost of tirthas and touching its water, became cheerful and happy. I have now told thee everything about which thou hadst enquired, how the divine Skanda was installed by the assembled gods!"
