One has to fill up the heart with Knowledge. The Knowledge has a form that's called 'upadesh' (nt: sub–country; also teaching, instruction). There are many countries such as England, Germany, and India, but Knowledge is not this kind of country. This country is something different. Knowledge is the thing that when it is realized, a person becomes free.
