Zen - Buddism

I found this text as an email signature of one of the professors who replied to me. Well the response was not as I expected, however, this text was worth noting.

"The Master in the art of living makes little distinction between his work
and his play, his labor and his leisure, his mind and his body, his
education and his recreation, his love and his religion. He hardly knows
which is which. He simply pursues his vision of excellence in whatever he
does, leaving others to decide whether his working or playing. To him he is
always doing both" - Zen Budddist
