Dhammapada 277-279

"All created things perish," he who knows and sees this becomes passive in pain; this is the way to purity. 

"All created things are grief and pain," he who knows and sees this becomes passive in pain; this is the way that leads to purity. 

"All forms are unreal," he who knows and sees this becomes passive in pain; this is the way that leads to purity.
