I have had at least 18,000 or so past lives. I remember many of them, some sort of blur together. Some totally forgotten. Some are quite similar, others are as different as day an night.
Each day is a new life, a new beginning, a new chance to look at things freshly, a new opprotunity to be free of "yesterday's stuff". The "life" I lived 30 years ago is quite different from my recent and current lives.
