Because Naropa was born a prince, was educated, and became a professor at NalandaUniversity, he regarded himself as . . . an educated, sensible person, someone highly respected.But this sensible quality, this sanity of his, turned out to be a very clumsy way of relating with the teachings of Tilopa - the teachings of the Kagyu lineage. Because he was not enough of a freak, because he was not insane enough, he couldn't relate with them at all. Insanity in this case is giving up logical arguments, giving up concept. Things as they are conceptualized are not things as they are.
