Om Swami
How can I be grateful to people who have hurt me?
Recall the good moments, even with those who hurt you
Be grateful even to those who have given you grief, because sometimes they must have done something right for you and there must be some good moments too. Nature does not hear complaints, but when you raise yourself to a higher platform of compassion, gratitude and selflessness, your voice reaches farther.
If you are with somebody and not happy with that person, it cannot be that all moments were bad. There must be some good moments as well.
