Put In The Fire

Rashi says תיעשה המנורה – מלא. לפי שהיה משה מתקשה בה, אמר הקב״ה: השלך הככר לאור והיא נעשית מאיליה. לכך לא נכתב: תעשה.  Moshe had a hard time understanding how to make the menorah so Hashem told him to throw it into a fire and it came out complete.  What was so difficult about the menorah specifically?  The Menorah represents the light of Torah (as discussed in the Netziv in detail.)  Moshe was astonished as to how one is supposed to be able to learn Torah in a manner in which it will illuminate the person and the world at large?  How can one merit to learn Torah in such a manner through all the difficulties one faces? Hashem answers thrown it into the fire, when one puts their energy into learning Torah, when one learns with a hislavus, then Hashem will give one the ability to understand and to penetrate the depths of the Torah so that it illuminates himself and the world at large (see Sfas Emes 5631.)
