Rationale of All Scriptures

Although the supersensuous vision of truths is to be met with in some measure in our Puranas and Itihasas and in the religious scriptures of other races, 
still the fourfold scripture known among the Aryan race as the Vedas being the first, the most complete, and the most undistorted collection of spiritual truths, 
deserve to occupy the highest place among all scriptures, command the respect of all nations of the earth, and 
furnish the rationale of all their respective scriptures.
