"When we harbor negative emotions toward others or toward ourselves,
or when we intentionally create pain for others,
we poison our own physical and spiritual systems.
By far the strongest poison to the human spirit
is the inability to forgive oneself or another person.
It disables a person's emotional resources.
The challenge is to refine our capacity to love others as well as ourselves
and to develop the power of forgiveness. "
