The farmer channels water to his land.

From the Dhammapada:

The farmer channels water to his land.
The fletcher whittles his arrows.
The carpenter turns his wood.
And the wise man masters himself.

I have been asked, "Does it get boring to do the same things over and over again?" What about the cutting and sanding that must be done if something is to be crafted with precision and care? The wise craftsman uses his attention wisely. He watches the transformation of material. He feels the texture as it moves from coarse to smooth. His mind never wanders, lest his intentions not be met. His attention is too precious to be wasted on the inconsequential wanderings of the common man.

As the farmer channels his water, as the fletcher whittles his arrows, and as the carpenter turns his wood, each works to master the landscape of self.

The mind wanders. The wise craftsman pulls it back into the moment and invests his attention in task at hand, that it may be done to convey wisdom and love.
