You ride on a horse,
while I ride on a donkey.
Looks like you are better off than me!
Turning around, I see a man pushing his cart.
Some are better off than me,
But there are others less fortunate than
myself!
A poem from the collection “Cloud and Water” (pdf) by the Chinese Buddhist writer Hsing Yun. The blurb explains the title of the book:
What do we mean by cloud and water? Clouds float by water flows on. In movement there is no grasping, in Ch’an there is no settling. The cloud and water life is a life of living in the moment, always fresh and ready to experience.
a reader's words 
the first poem reminds me of the idea that “your happiness is relative to the happiness of other people”. 🙂
just a related observation, that’s all.
