I read this story in the book "A New Earth" by Eckhart Tolle. And here is what i remembered in my own words...
Once there are two monks walking back to their monastery. They came across this girl trying to cross a puddle of water in her kimono.
So one of the monk picked up the girl and help her across the puddle.
Then the two monks continued their journey.
When they reached the monastery about four hours later, The other monk said, "I can't believe that you actually carry the girl, we are not suppose to touch girls."
The monk replied. "I have put her down 4 hours ago, why are you still carrying her in your mind."
How many of us have consciously or unconsciously chose to carry emotional "baggage" with us?
Also, after the event has passed, we chose to replay it over and over in our minds to invoked the same emotions again and again.
It is kind of like, people do it to you once. Then you choose to replay it to your mind, and you do it to your self countless more times.
At times when we catch ourselves reliving some past event to bring about negativity in us. Think about the story of the two monks and think about letting go.
