A Zen student is washing dishes in the community kitchen as the master walks in.
The student waves at the large pile of plates and complains how much work it is:
“Look, master, there are so many plates to wash!”
“How can you wash all the plates?” asks the master.
“Well, look,” says the student.
The teacher shakes his head and says, “You can only wash one plate – this one.”
Similarly, when we have a big project, we get tired just thinking about the amount of work required to accomplish it. In reality, we can only do one thing at any moment. Building a house is a huge project, but one can only focus on placing one brick at a time.
