A morning musing on the similarities of art and religion lead me to this excellent quote from St Francis Assisi:
He who works with his hands is a labourer,
He who works with hands and mind is a craftsman,
But he who uses hands, mind and heart together is an artist.
To me these are just different levels of concentration:
Conscious
Mindful
Enlightened
And the joy of zen is to know enlightenment is present in every moment so you can be an artist always :)
