Rabbi Judah ben Bezalel Lowe, known as the Maharal of Prague was famous among Jews and non-Jews alike. He was a mystic who was revered for his holiness and Torah scholarship, as well as his proficiency in mathematics, astronomy, and other sciences. Eventually, word of his greatness reached the ears of Emperor Rudolph II.
The Emperor invited the Maharal to his castle on February 23, 1592. There they conversed for one and a half hours, and developed a mutual respect for each other.
Rabbi Judah Lowe made use of his excellent connections with the Emperor, often intervening on behalf of his community when it was threatened by anti-Semitic attacks or oppression.
Sometimes you look at yourself in the mirror and you feel unqualified. You know yourself, your failures and your faults, and you don't feel like you could be a model for others.
You say, "I should teach others? I should provide guidance?!"
So we tell you, “Yes. Because that is your place upon this planet: We live in a time when all those who know Alef must teach Alef and those who know what comes after Alef must teach that too.”
“And G‑d Above, who formed you and put you in the here and now, He knows who you are and how you are and what you are capable of accomplishing. If He believes in you, you must as well.”
Teach others and become great.
