When we refer to G‑d’s presence within our world, giving life to all things, then She is the Shechinah.
When we refer to G‑d’s transcendence beyond this world, we call Him “The Holy One, blessed be He.”
In our prayers, collectively our souls take the role of the Shechinah, petitioning the Holy One, blessed be He.
Our mitzvahs, our Torah study and our prayer unite these two aspects of G‑d into a perfect whole. Through them, we reveal the essential G‑d who is beyond both the immanent and the transcendent—beyond all description and bounds.
And that is what we mean when we say, “On that day, G‑d will be One and His name will be One.”

Everybody knows they have a “self”. It is the whole world to us.
Then we suffer from failures and misunderstandings. We look for better, for perfection, over our lifetime. Without realizing it we try to exchange the self for the perfect Self. For that we need to let go of our “self” and accept our REAL Self, and everything is great.
We try hard to keep that “level”, and realize all is the “here and now”. This is never lost again.
We then abide in the Self, because we realize that there is no other Actuality but what IS. Then we seek more understanding and depth forever.
Just realize the word is not the actual thing, and keep focusing on that.
