Who is the Boss? by Gambhiro Bhikku is a humorous book introducing the concept of no-self for kids. The book is richly illustrated and it gets a bit weird since it takes place in the annual meeting at the Organs-ization, where the organs try to decide who is the boss of the body. From the book:
Without a self, no confused Kamma can be created and so no retributive suffering can follow. One is free, nowhere attached, without the delusion of self. The truth is there is no boss.
