The Fashioner, his son being slain, offered the provision without the Mighty. The Mighty desired an invitation to the rite, but he was not invited. He made a disturbance of the sacrifice, and drank the provision by force. The remains of it the Fashioner cast upon the Ahavaniya fire, saying, "Hail! wax great, foe of the Mighty." In that he cast it, Vritra is Vritra; in that he said, "wax great, foe of the Mighty," therefore the Mighty became his foe. He sprang into life. He grew on all sides an arrow's shot, he enveloped these worlds. Because he enveloped these worlds, therefore is Vritra, Vritra. The Mighty feared him. He ran up to the Creator, saying, "A foe has sprung up for me." He dipped his bolt and gave it to him, saying, "Slay with it." He went against him with it. The Radiant and the provision said, "Hurl it not; we are within." "Ye are Mine," he replied, "come to me." They asked for a share; he gave them at the full moon this offering for the Radiant and the provision on eleven potsherds. They said, "We are bitten all round, and cannot come." The Mighty produced from himself cold and fever heat; that was the origin of cold and fever heat. One who knows thus the origin of cold and fever heat is not slain by cold or fever heat. By them he led him on, and as he gaped the Radiant and the provision went forth from him. Then expiration and inspiration deserted him; skill is expiration, intelligence is inspiration; therefore one who gapes should say, "Skill and intelligence remain in me"; thus he places expiration and inspiration in himself and lives all his days. Having called off the angels from Vritra he offered at the full moon the oblation to the Vritra slayer; they slay him at the full moon, but make him swell at the new moon; therefore verses are uttered at the full moon referring to the slaying of Vritra, at the new moon referring to his increase. Having performed the oblation to the Vritra slayer, he took his bolt and again went against him. Sky and earth said, "Hurl it not; he rests in us two." They said, "Let us choose a boon." "May I be adorned with the stars," said yonder sky; "May I be adorned with variegated things," said this earth. Therefore yonder sky is adorned with the stars, this earth with variegated things. One who knows thus the boon of sky and earth attains a boon. The Mighty, thus impelled by these two, slew Vritra. The angels having slain Vritra said to the Radiant and the provision, "Bear the offering for us." They said, "We two have lost our brilliance, our brilliance is in Vritra." They said, "Who is there to go for it?" "The cow," they said, "The cow is the friend of all." She said, "Let me choose a boon; ye shall feed off both when they are in me." The cow brought the brilliance; therefore they feed off both things that are in the cow; ghee indeed is the brilliance of the Radiant, milk the brilliance of the provision. One who knows thus becomes brilliant. The theologians say, "What is the object of the full moon rite?" He should reply, "The Creator; by means of it He established His eldest, the Mighty." Therefore they establish their eldest sons with wealth.
