Suffering lessens when we start to look in the direction of truth.
So, what is truth?
Our realities are thought created.
To put it another way, we live in the feeling of our thinking.
Whatever thoughts we are having (consciously or unconsciously) we will feel them.
We all experience a different reality.
When we see through the illusion we have created about life, via our thoughts, truth shines through. When truth shines through suffering lessens and a new path becomes apparent.
