“Even implacable foes of past lives
Have become friends in this life, and done me service.
Past lives’ friends, too, become in this life
Real foes, who even attack my life.
Even in this life, from early to later parts,
In every year and month and day,
And moment by moment, friends and foes change.
What can you trust about helping and harming?”
