Being cheerful is like a butterfly!  
If you try to catch the butterfly 
by following it very seriously;  
 
it will be flying further and further,  
You can’t catch it for ever,  
You will be tired getting a feel, sour!  
 
If you keep sitting quietly,  
The small creature, butterfly 
will sit on your shoulder naturally!  
 
Searching and chasing more 
in the outer world for cheers,  
you can’t fetch it in your hands!  
 
If you cultivate the habit of being 
kind, quiet and prudent, cheers will stick  
on to you permanently like butterfly!
