Since your mind
is a creation of God, God must have knowledge of
your brain's existence.
In knowing all about your brain, He certainly knows what's on your mind.
You just can't get around that -- God know's what's on your mind.
God's creation of the world is a continual process that is going on at every moment of this world's existence. You can't get around that -- God, is actively involved in the world's every process, and the only reason this world doesn't wiggle out of existence is that God sees fit to keep it here.
When you donate part of your braintime back to the brain's maker, God, you're more able to achieve new growth and new realizations about your identity and your potential. And, for the duration of the time you've got something "Godly" on your mind, (perhaps a chapter of Tehillim) you resonate with the highest potentials that can exist in this world.
Yichud is the ultimate state for everyone, Jew or Gentile. Jews in their way, Gentiles in their way. Jews doing their Mitzvot, and Gentiles doing theirs (you can search in google.com for information on the Seven Mitzvot of the B'nei Noach).
We're all preparing for better days. The days of the Jewish "redemption" (read the right column on the Abarbanel page).
Everyone can discover their own aspect of connection to G-d, and then continue to fortify that connection.
It does not mean a person must reach perfection to understand G-d. It means you're supposed to enjoy trying and as you make your efforts, you actually can understand how G-d is working with you and see it in your life.
