People who really have
Their minds on the Way
Do not forget work on the fundamental 
No matter what they are doing. 
Yet if they still distinguish this work
From ordinary activities 
Even as they do them together, 
They will naturally be concerned
About being distracted by activities 
And forgetting the meditation work. 
This is because of viewing 
Things as outside the mind.
