15th of Av one of the two most auspicious days on the Jewish calendar

Our sages regarded the 15th of Av to be one of the two most auspicious days on the Jewish calendar (the other being Yom Kippur -- Talmud, Taanit 26b).

Moshe Rabbenu and Torat Moshe

Willing to communicate with mankind the Elohim giving them His Torah shot his arrows at mankind [y-r-h, "to shoot (an arrow),"] and gave them a first teacher or instructor of God's Laws, hence also often called Torat Moshe. Moshe not writing down a Fable or Fairy tale, but bringing a real life story of man or history of the peoples in an easy way to remember.
