Taoist Master Danyang once said,
"Students of the Way should have their minds on the Way at all times, no matter what they are doing.
When they walk, they set foot on the path of evenness.
When they stand still, they freeze their feelings in cosmic space.
When they sit, they tune the breathing in the nose.
When they recline, they embrace the jewel below the navel.
Eventually the tune of the breathing is unbroken, and you are like a quiet fool all day long.
This is the correct practice - it has nothing to do with contrived observances."
