The "falling out" of God and Moses was repaired through Moses' prayers and the building of the Temple. When the Temple was finished, God called Moses for a conversation.
In Hebrew, "he called" is Vayikra, וַיִּקְרָא.
The Alef, which used to signify 1,000 and measured the light of Moses' face, became small. It was reduced 1,000 times. That was the effect of the Golden Calf. The Torah, spelling the letter alef small, reminds of the previous problematic act.
Moses (Moshe) represents two spiritual entities who give birth to the souls of the righteous. The summary of the calculations shows that the name Moses is the sum of these two spiritual entities:
אחור יסוד אבא
פנים יסוד אמא
קפד = 184
קסא = 161
345 = םשה (Moshe)
Using these and other connections, Kabbalists give meaning to the words of their prayers and make them more powerful.
