Katie says:
"I discovered that when I believed my thoughts, I suffered, but that when
I didn't believe them, I didn't suffer, and that this is true for every human
being.
Freedom is as simple as that. I found that suffering is optional.
I
found a joy within me that has never disappeared, not for a single moment. That
joy is in everyone, always."
May you be well and happy always.
