9.42.38

tatrāpyupaspṛśya balo mahātmā dattvā ca dānāni pṛthagvidhāni |
avāpya dharmaṃ paramāryakarmā jagāma somasya mahatsa tīrtham || 38 ||

Vaishampayana continued, "The high-souled Baladeva having bathed in that tirtha and given away many kinds of gifts, obtained great merit. Of righteous deeds, he then proceeded to the great tirtha of Soma. There, in days of yore, Soma himself, O king of kings, had performed the Rajasuya sacrifice. The high-souled Atri, that foremost of Brahmanas, gifted with great intelligence became the Hotri in that grand sacrifice. Upon the conclusion of that sacrifice, a great battle took place between the gods (on the one side) and the Danavas, the Daityas, and the Rakshasas (on the other). That fierce battle is known after the name of (the Asura) Taraka. In that battle Skanda slew Taraka. There, on that occasion, Mahasena (Skanda), that destroyer of Daityas, obtained the command of the celestial forces. In that tirtha is a gigantic Aswattha tree. Under its shade, Kartikeya, otherwise called Kumara, always resides in person."
