Not by toil, nor by struggle did the world come into being. G‑d spoke and it was, a world created by words.
Not by toil, nor by struggle is the world sustained. We speak words of Torah, of prayer, of wisdom and of kindness, and the world endures.
If so, what is the effort He demands from us?
That we invest our very essence in those words, as He invested His very essence within this world He made.

G-d is the only Self, and in the Mind of this Self is what is known as the Creation, or the Formation of what IS. Humans were formed, in His Image, on the 7th “day”, and tested with a simple test which was a deliberate failure, IMO, to stimulate their spiritual flowering to fruitful success.
We need Him in our Hearts, as our Deepest Actuality, but how do we make that happen? On the left side of our chests is the organ known as the heart, beating and circulating life blood through our bodies. But, believe it or not, this is not the required heart. The deeper, spiritual heart can be found on the right side, not physical but spiritual in nature, and/or behind the head where we can listen to the Divine Call. It is there that we learn to identify as “I AM”, after we let go of the big error, of “me is”. There is only one Self. Remember, the word is not the actuality it describes. That is only the Divine Words, from the “Divine Mouth” speaking in our innermost "Heart".
Sorry, I get things turned around sometimes. Man was made on the 6th day, not the 7th. Pray for my typing ability please.
