Venerabel Vasistha, the best amongst the knowers of the Vedas, skilled in mantras and firm in his vows said to the king, 'Be it so.' Thereafter, mounted on the best of the chariots befitting a brahmin, with horses harnesed he proceeded personally to the abode of Rama to ask him to undertake a fast in accompaniment with mantras preceding the installation ceremony.
— M.N. Dutt (1891)
Vasistha's response is repeated and affirmed. In the epic's oral tradition, such repetition marks the importance of what is being said. The priest's acceptance seals the plan: the spiritual and temporal authorities are united. Nothing stands in the way.
