“Get my chariot at once Do not delay. I shall start today itself.” Vasiṣṭha, the royal preceptor, must be at the head of the procession along with the mothers or Rama and his wife and all the fires.
This shloka emphasises the pre-eminent position of the preceptor, as well as the sacrificial fires of the Grihasthāshrama. No travel was even made without these fires! It was common practice, till a few decades ago, to carefully preserve the fires from vivāha till the end!
