Is it to find the meaning of life?
Is it to find your self?
Is it to get rid of the Self itself?
Is it to become a better person?
Is it to become a greater person?
Is it to become enlightened?
Is it to become at all?

Maybe the ‘Autobiography in Five Chapters’ from The Tibetan Book of Living and Dying can shed some light on spiritual growth:

1
I walk down the street
There is a deep hole in the sidewalk
I fall in.
I am lost. I am hopeless.
It isn't my fault.
It takes forever to find a way out.

2
I walk down the same street.
There is a deep hole in the sidewalk
I pretend I don't see it.
I fall in again.
I can't believe I'm in the same place again.
But it isn’t my fault.
It still takes long time to get out.

3
I walk down the same street.
There is a deep hole in the sidewalk.
I see it is there.
I still fall in� it's a habit
My eyes are open
I know where I am
It is my fault.
I get out immediately.

4
I walk down the same street.
There is a deep hole in the sidewalk
I walk around it.

5
I walk down another street.
