“The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal.” -Aleister Crowley
But the Universe itself experiences continual growth, constant change, and new experiences all the time, and it does so spontaneously.
