In the Prabhasa-khanda of the Skanda Purana (5.3.121-124) it is said –
veda-van niscalam manye puranartham dvijottamah
vedah pratisthitah sarve purane natra samsayah
bibhety-alpa-srutad vedo mam ayam calayisyati
itihasa-puranais tu niscalo’yam krtah purah
yan na drstam hi vedesu tad drstam smrtisu dvijah
ubhayor yan na drstam hi tat puranah pragiyate
yo veda caturo vedan sangopanisado dvijah
puranam naiva janati na ca sa syad vicaksana
" O best of the brahmanas, the meaning of the Puranas is unchanging just like that of the Vedas. The Vedas are all sheltered within the Puranas without a doubt. The Veda has a fear that unqualified people will read her and then distort her meaning. Thus, the significance of the Veda was fixed in the Puranas and Itihasas. That which is not found in the Vedas is found in the Smrti. That which is not found in the Smrti is to be found in the Puranas. Those who know even the Vedas and Upanisads are not learned if they do not know the Puranas."
