Likutei Moharan 11:9/ליקוטי מוהר"ן י״א:ט׳

19. And this is [the explanation of the opening verse]: {“Ani YHVH (I am God), that is My Name. My glory I shall not give to another, nor My praise to idols.”}

2Ani YHVH — [“YHVH” is] the upper unification.

3that is My Name — [“My Name” is] the lower unification.

4My glory I shall not give to another — This corresponds to glory that is complete.

5nor My praise to idols — This corresponds to speech. As is written (Psalms 145:21), “My mouth will speak God’s praise.” This has all been explained.
