"... and somehow the word Joy became the most unmeasurable word.
It was the essence of creativity, the force of creativity.
I realized that if I were a painter about to paint a great catastrophe,
I could not put the first stroke on canvas without thinking of Joy in doing it.
you cannot make a building unless you are joyously engaged.
I would like to feel that I have not forgotten, nor have you as I speak to you,
about the stream of Joy which must be felt.
Otherwise, you really don't feel anything..."
/ Louis Kahn/ .
