Regardless of how long we spent living together,

Good friends and relations must someday depart.
Our wealth and possessions, collected with effort,
Are left far behind at the end of our life.
Our mind, but a guest in our body’s great guest house,
Must vacate one day and travel beyond.
Cast away thoughts that concern but this lifetime —
The Sons of the Buddhas all practice this way ~  # 4 of The Thirty-Seven Practices of a Bodhisattva
