When he came to Baso he again said, ‘Who is he that is independent of all things?’ Baso said, ‘When you have drunk all the water in the Yang-tze river, I will tell you.’ At this, Koji underwent his great experience and composed another verse:” (Two Zen Classics 263)
Spring comes with its flowers, autumn with the moon,summer with breezes, winter with snow; when useless things don’t stick in the mind, that is your best season.
-Wu-men Huai-kai
