Book Smarts Versus Street Smarts

“Jnana means theoretical knowledge, and vijnana refers to practical knowledge. for instance, a science student has to study theoretical scientific conceptions as well as applied science. Theoretical knowledge alone will not help. One has to be able to also apply this knowledge. Similarly, in yoga one should have not only theoretical knowledge but practical knowledge.” (Shrila Prabhupada, The Perfection of Yoga, Ch 5)
