“The gods do not speak with everyone,” and so a way has to be devised to approach them: men must segregate themselves in the same way as the gods are segregated from men. Then perhaps the gods will pay attention. An initial separation from other men is achieved through the preliminary actions of the rite.
When setting up the gārhapatya fire, he first sweeps the chosen space with a palāśa branch and says: ‘Away from here! Away! Crawl away from here,’ then: ‘Go away, go and slip away from here,’ he says to those who slither on their bellies. ‘You who are here from ancient and recent times!’ and therefore both those who are here from a remote time as well as those who have settled here today.”
The ritual action is an imitation. Of other men, who lived in the beginning? Or of gods? During the building of the fire altar when certain bricks, known as dviyajus, “which require a double formula,” have to be arranged. At that moment the sacrificer thinks the following words: “I wish to go to the celestial world following the same form, celebrating the same rite that Indra and Agni used to enter the celestial world!” What the sacrificer is imitating is the act of the god himself making himself a god
Ritual serves above all to resolve through action what thought alone cannot resolve. For example: what do we do with the ash produced by the sacrificial fire? The ashes are thrown into water. And these words are spoken: “O divine waters, receive these ashes and place them in a soft and fragrant place!” And then: “May the consorts, married to a good lord, bow down to him.” The “consorts” here are the waters, who have found a “good lord” in Agni. The waters are chosen as a place for ashes, because Agni was born from the womb of the waters.So Agni will not be lost.”
