There are many famous but one of my favorites is:
"A truly compassionate attitude toward others does not change
even if they behave negatively or hurt you." Dalai Lama
We all come across people who hurt us or behave negatively. Perhaps our first reaction is to lash out at them. Or, become angry with them. Especially when we feel hurt or disappointed. But the Dalai Lama's words are ones that could be considered as a quote to live by as if we maintain a compassionate attitude we are not feeding into the negativity of the individual.
When people respond with a negative attitude or they do something to hurt, it truly is them who has the problem. They have some issue that they need to resolve, and the issue is not you it is within them.
Surround yourself with positive people, people who encourage and appreciate you. Don't let your energy be consumed by those with a negative attitude - life is just too short. Showing compassion and feeling sorry for the individual will take away your anger and hurt, but there is no need to be subject to their negativity!
So the next time you are feeling hurt by others remember this wonderful quote by the Dalai Lama!
