there are two kinds of knowledge, the higher and the lower.
"The lower is knowledge of the Vedas (the Rik, the Sama, the Yajur, and the Atharva), and
also of phonetics, ceremonials, grammar, etymology, metre, and astronomy.
"The higher is knowledge of that by which one knows the changeless reality. By this is fully revealed to the wise that which transcends the senses, which is uncaused, which is indefinable, which has neither eyes nor ears, neither hands nor feet, which is all-pervading, subtler than the subtlest-the everlasting, the source of all.
