Man possesses a number of angas or limbs. In the same way the Vedas personified -- the Vedapurusa -- has six limbs.
The four Upangas, though not integral to the Vedas, are supporting limbs of the Vedapurusa.
Vedas are seen in a different form in the Ramayana, the Mahabharata
and the works of poets like Kalidasa.
Ramayana Vedavedye pare pumsi jate DasarathatmajeVedah Pracetasadasitssaksadramayanatmana
"Vedavedye"=one who is to be known by the Vedas. Who is he? "Pare
pumsi"=the Supreme Being. The Supreme being to be known by the
Vedas descended to earth as Rama. When he was born the son of
Dasaratha, the Vedas took the form of Valmiki's child Ramayana.
BG 15.15 The lord says in the Gita:"Vedaisca sarvair ahameva vedyah"(I am indeed to be known by the Vedas)
If the Puranas are described as constituting an Upanga of the Vedas, the
itihasas(the epics) are so highly thought of as to be placed on an equal
footing with the Vedas. The Mahabharata is indeed called the fifth Veda
("pancamo Vedah")
Vedangas and Upangas complement vedas , (are vaidika वैदिक - never away from quintessence of Vedas ), are different expressions of Vedas in various other ways
