From the Song-dynasty Chan master
无门慧开 (1183-1260), in 《
无门关》:
春有百花秋有月,夏有凉风冬有雪。若无闲事挂心头,便是人间好时节 (Spring has a hundred flowers, autumn has the moon; summer has cool wind, winter has snow. If no idle worry hangs on your mind, this is the world's best season). A Chan verse teaching presence - every season is complete if the mind is clear.
