no giver, no receiver, no gift
In the Zen tradition a priest sews his own robe along with what is called a zagu or bowing mat. The mat is opened and placed on the floor for the priest to bow down on.
It is a cloth to remind the priest as well as others who witness the bowing of two messages:
The first message is to remind the priest of the torn rags he used to sew the cloth. Nothing is useless.
The second is to remember the whole world bows on the cloth with him. No one is left out.
All one cloth. Nothing is useless. No one is left out.
