"Self-perfectment is the most difficult achievement. People inject into this process so many inconsistencies that the manifestation of true self-perfectment is obscured... Take the history of humanity. Observe how brief were the periods of materialism; they invariably ended in bloody convulsions. Indeed, the trend of thought became rebellious, and the correct path having been lost, crimes multiplied. Self-perfectment is possible only through refinement of consciousness by its seeking to surround itself with worthy manifestations."
