宋代无门慧开禅师《
颂》(Song-dynasty Chan master Wumen Huikai, 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.
