The mind becomes one with the thought of the Eternal. There is the unification that occurs twice each day and even beyond this becomes a way thinking about God as singular and contained within itself. There must be continuity of focus and a singularity of thought. This is something that is the inheritance of consciousness; that consciousness that began with the revelation of I Am.
Now out of this revelation of I am, the awareness of being, of process and of form there arises self reflection. However, this self reflection becomes clouded by those extraneous thoughts as motes of dust will cloud a mirror giving an imperfect image. Just as we wipe those motes of dust away with a cloth to reveal the perfection of the image so too can we operate in thought to remove everything that clouds our image of the divine.**
During our recital of the SHMA twice a day there is the opportunity to remember this singularity of thought and to apply to the experiences of our lives. The SHMA represents the unification of Shekhinta and Qudsha Brikh Hu. This unification ties together our aspirations on high with the complete application to all that is around us. We do not just unify in some ethereal plane but are rather unified throughout the entire experience of being.
(Proverbs 19:21) Many are the thoughts in the heart of a man… We have to recognize that the world around us provides us with so many directions and that those directions all lead to dead ends except for the one that unifies above and below. This unification is the awareness of connection and its source and then the unity that exists forever between the two who are always one.
This is the central idea that Torah is teaching us. If we were learn nothing else it would be enough to spark every single revelation because all flows from this one concept of the singularity of thought.
