You can think of emptiness as what remains when you have removed every thing which could ever have received any kind of name or description, even simply in thought or imagination.

Among the 14 lines of your letter, for instance, you mention earth, compassion, life, qualities, conclusion, art, flowers, view, thought, perceptions, experiences, observed, I…

Whether noun or verb, real or unreal, substantial or insubstantial, all named things are the creation of the psyche, even our idea of emptiness (or sunyata) itself. If there were no minds in the universe—or if the universe was empty—none of these things could be said, or thought, to be.

These things appear to be; but in the ultimate sense none of this is unchangeably real. Not even the I, with its psyche. No more lasting reality than appearances in a dream are real.

So, what questions, ultimately, do we need to answer?

As you said, “Emptiness sure sound empty.” Even more than we can imagine.
