Chassidic master Rabbi Dovid Biederman of Lelov (1746-1814) was a disciple of the "Seer of Lublin." Rabbi Dovid was known for his extraordinary ahavat yisrael; it was said of him that he was incapable of seeing faults in a fellow Jew. Two printed collections of stories about him are Migdal David and Kodesh Hillulim.

Once a month, as the moon waxes in the sky, we recite a special blessing called Kiddush Levanah, "the sanctification of the moon," praising the Creator for His wondrous work we call astronomy.
Kiddush Levanah is recited after nightfall, usually on Saturday night. The blessing is concluded with songs and dancing, because our nation is likened to the moon—as it waxes and wanes, so have we throughout history. When we say this blessing, we renew our trust that very soon, the light of G‑d's presence will fill all the earth and our people will be redeemed from exile.
Though Kiddush Levanah can be recited as early as three days after the moon's rebirth, the kabbalah tells us it is best to wait a full week, till the seventh of the month. Once 15 days have passed, the moon begins to wane once more and the season for saying the blessing has passed.

What is a mitzvah?
An act of uniting heaven and earth.
But heaven is spiritual and earth is material. To make spirit and matter one is impossible!
A creature of earth cannot make earth heaven. And a heavenly being cannot bring heaven to earth.
But for you, it is not impossible.
This mitzvah that I am commanding you today is not impossible for you. It’s not even distant. It’s very close to you, in your mouth and in your heart to do it. (Deut. 30:11)
It is close to you because the Torah was given to you both written and orally. (Rashi)
Because within you breathes the Creator of both heaven and earth.
So that when you speak the words of His written Torah, you bring heaven down to earth.
And when you explain the words of His oral Torah, you bring earth up to heaven.
Indeed, you accomplish the impossible every day.
