Koans...They break my brain

I enjoy a good riddle, but koans are quite frustrating: they have no answer! With a riddle, there is a rational answer at the end, but koans have no proper end! 

Exemple: this affirmation is false!…so if it’s false, its right to say it, so it become true. But if it’s true, them its not false anymore and therefore become false again, and true, etc….



Useful links! Take a look at them!


A archive of 99 koans, translated into English, from a book called the Shaseki-shu (Collection of Stone and Sand) from the thirteenth century and some other place.


A lot of thing here! Tons of Koans with comments and studies about them if you wanna go further!
