Presently, you KNOW you are. This knowledge of I AM, has given you this sense of being. You have taken this knowledge to be real and because of it, you are suffering. One has to question as to how this knowledge of beingness came about. What were you prior to this knowledge of beingness? Unless these questions are inquired into, the final answer will not come about. Did you do anything to attain this knowledge, I Am? You may wonder, "if this knowledge, I Am, is not the Reality, then what use is it?". Don't dismiss this knowledge I AM. In fact, the ultimate purpose of this knowledge I Am, is for you to unravel the mystery of how this all came about. In fact, I Am is your God and this God is going to pave the path to Self Discovery and Self Realization. So, hang on to the I Am for it is everything.
What you really, really ARE is beyond the knowledge I Am. Since, there is no description for that State, it is simply called THAT or the Absolute. In THAT, there is no I Am. It is beyond I Am. It is beyond all dyads and triads. Because, it is a State prior to consciousness and thereby the mind, it is impossible for the limited mind to fathom what by nature is beyond both limited and unlimited. When one says "I am That", one acknowledges the fact that I Am is a derivative of THAT. There is no way for one to know THAT in the objective sense, since IT is beyond both the subject and the object. You are none other than THAT. Just reach this Understanding.
