Ohr Ein Sof אור אין סוף
lit.: endless light
1. An energy capable of generating time, space, consciousness, matter, beauty and diversity without end.
2. An endless mystery found in all things.
3. Both of the above.
4. A name of G‑d in classic Jewish texts.
Example: “Having contemplated the sacred teachings, Miki’s soul yearned to be re-absorbed within the Infinite Light.”

Since learning more about the soul, my previous comment below needs to be revised or even scrapped! But I will leave it there, to show you how I have learned to change my mind,
Writers about the subject of EIN SOF and the human soul should be very careful about how they express these ideas, particularly to a young and doubting audience. This is shown up by the few comments below.
I now believe I can answer one of them about communication with one's soul. This method is through what is perhaps more commonly known as our conscience. We somehow have within our minds a part that when we listen to it tells us what we should be doing.
It is as simple as telling us to get out of bed in the morning, and more involved when we feel slightly guilty through not giving much or any charity to beggars in the street, So, although many persons like you may not want to accept this claim, we do have the means and frequently do give certain answers to what our souls are asking.
Love and best wishes
This is very deep to ponder. I think you are correct. Thank you for sharing your insight.
