To whom does a Jew pray?

Can He be described? Does He have a name?

No, there is no description with which to imagine Him, no name with which to grasp Him.

Even the pronoun “Him” implies too much to be true—as though He could be a third party, absent or present. Even the title “Infinite Light” misses the mark, as though He were only light.

But He is not light. He is the source of light. At the source of all light, there is no absence or presence, no being or not being.

There is only “You.” Here, now, known to all beings. And yet beyond the grasp of any knowledge.

It is truly inconceivable, certainly outrageous, but we puny, mortal creatures turn to the heavens and beyond the heavens and say, “You.”

As Rabbi Yosef Yitzchak of Lubavitch wrote:

You, that all know of You.

You, that all put their trust only in You.

You, that all plead only to You.

You, that no creation nor emanation knows who and what You are.

And so we pray to You alone, for You alone, the Unknowable, are known to all.
