Buber and the Rashab walk into an Aleinu

Jewish meditation begins with desire -two distinct beings wanting relationship. 
Practicing davening and meditation, the lines of distinction blur. 
I and Thou become I/Thou. 
Eventually, ego begins to fade. 
As "I" dissipates, the distinction of "Thou" fades too. 
At the ecstatic  height of Jewish meditation, no distinctions are left to be made.
There is no "I" or "Thou". 
So what is left? 
אֶפֶס זוּלָתוֹ.
(There is none else)
אֵין עוֹד
(There is none other)
