There is a difference between the Vedas – plural – and the concept of Veda.
The Vedas (Sanskrit: वेद véda, "knowledge") in plural are texts, actual documents, originating in the ancient Indian subcontinent. Composed in Vedic Sanskrit, the texts constitute one of the oldest layers of Sanskrit literature and the oldest scriptures of Hinduism. Hindus consider the Vedas to be apauruṣeya, which means "not of a man, superhuman" and "impersonal, authorless".
But the word Veda has nothing to do with the religious texts known by this name.
The notion of Veda represents the belief in a universal law, the object of knowledge. In other words, the Veda is the System of the Universe, that which animates – the functions and entities.

This implies the acceptance of the idea that there exists a divine order of the world of which it is possible to have a fragmentary glimpse, an "approach" (upanishad), even though this order remains on the whole unknowable.
No one can pretend to possess the "truth" in any domain. A dogmatic teaching can be neither scientifically nor philosophically nor morally justifiable.
