When I think that my past is bad, I will try to forget it.
No one likes bad things.
With the result that I will deny my past and then become ill.
When I think that my past is very good, I will try to preserve it's memory and love my past.
Then when I get attached to the past I start to miss the past and ultimately I will become ill.
We need to understand that my past is not good or bad, but that it is natural and the concept of good and bad is attached to my body.
For example, when I drive a car - this is a good thing.
I turn the wheel - that is a good thing as well.
But if the car were to fly into a ditch - this would be a bad thing and I would need to repair it.
Our understanding of good and bad is attached first of all to our bodies and to the interests of our bodies.
This is why when we feel that we have been harmed, our reaction is to think whether to forgive or not.
