Be silent and listen: have you recognized your madness and do you admit it? Have you noticed that all your foundations are completely mired in madness? Do you not want to recognize your madness and welcome it in a friendly manner? You wanted to accept everything. So accept madness too. Let the light of your madness shine, and it will suddenly dawn on you. Madness is not to be despised and not to be feared, but instead you should give it life...If you want to find paths, you should also not spurn madness, since it makes up such a great part of your nature...Be glad that you can recognize it, for you will thus avoid becoming its victim.

Stupidity is when you won't fear God but you will fear the Frog.
