Indeed one has to say: a certain seriousness of life begins, when higher knowledge starts to be attained. And even if one obtains nothing else there is one thing one acquires: one learns to recognise one’s own vices and imperfections with infinite clarity. One could say: one acquires an experiential understanding of imperfection and wickedness already during the first steps on the road to the spiritual world.
