The personified Vedas are just like great sages in appearance. Some of them may be looking like Vyasadeva, Valmiki, Narada, etc. Some of them are older and some of them are younger, some of them have full hair like Vyasa because they are householders and others are brahmacari - but they are all great souls, highly elevated in transcendental science, or Paramahamsas.
