I noticed this building today. I have known this block of flats for many years, passing it on my way to work about 10 years ago. 

It is being refurbished. 

It is being given a new lease of life from the rather grim block of flats it used to be. 
That reminded me that in samsara, things wear out and need repair. Nothing is permanent. 

Why devote your life to building things that are not permanent?

May we all build permanent freedom for suffering and permanent happiness in our minds.
