A man can only attain knowledge with the help of those who possess it. This must be understood from the very beginning. One must learn from him who knows.
All religions speak about death during this life on earth. Death must come before rebirth. But what must die? False confidence in one's own knowledge, self-love and egoism. Our egoism must be broken.
Religion is doing; a man does not merely think his religion or feel it, he 'lives' his religion as much as he is able, otherwise it is not religion but fantasy or philosophy.
Without self knowledge, without understanding the working and functions of his machine, man cannot be free, he cannot govern himself and he will always remain a slave.
