birth

"This body is not me"

I read these great lines in a Buddhist chanting book today:

This body is not me.
I am not limited by this body.
I am life without boundaries.
I have never been born,
and I have never died.

I wonder how many people read those lines and really believe them? I don't know why most people become Buddhists, but I consider myself very fortunate to have had many experiences where I can read these lines and at least feel like I know what they mean.
