What does Vedas consist of?

Here is a description about the contents of Vedas as given by the Smrithis.

The Veda is the eternal eye of the ancestors, gods, and men. The Veda-ordinance is both beyond the sphere of human power, and beyond the sphere of both human power & comprehension. All those traditions and those despicable systems of philosophy, which are not based on the Veda, produce no reward after death; for they are founded on Darkness. All those doctrines, differing from the Veda, which spring up and soon perish, are worthless and false, because they are of modern date. The four castes, the three worlds, the four orders, the past, the present, and the future are all severally known by means of the Veda. Sound, touch, colour, taste, and fifthly smell are known through the Veda alone, their production is through the Vedic rites, which in this respect are secondary acts. The eternal lore of the Veda upholds all created beings. Command of armies, royal authority, the office of a judge, and sovereignty over the whole world he only deserves who knows the Veda-science. As a fire that has gained strength consumes even trees full of sap, even so he who knows the Veda burns out the taint of his soul which arises from evil acts. In whatever order a man who knows the true meaning of the Veda-science may dwell, he becomes even while abiding in this world, fit for the union with Brahman. [3]
