You cannot possibly say that you are what you think yourself to be!
Your ideas about yourself change from day to day and from moment to moment.
Your self image is the most changeful thing you have. It is utterly vulnerable, at the mercy of a passer by.
To know what you are you must first investigate and know what you are not.
And to know what you are not you must watch yourself carefully, rejecting all that does not necessarily go with the basic fact: 'I am'.
Separate consistently and perseveringly the 'I am' from 'this' or 'that', and try to feel what it means to be, just to be, without being 'this' or 'that'.
The clearer you understand that on the level of the mind you can be
described in negative terms only,
the quicker you will come to the end of your search and realise your limitless being.
