The "Counting of the Omer" is a Jewish tradition that occurs between the second night of Passover and the holiday of Shavuot. It involves counting each of the 49 days, which represents the period of spiritual preparation leading to the giving of the Torah at Mount Sinai. During this time, many people recite a specific blessing and count the day each evening. The practice emphasizes themes of growth and reflection, as individuals work on personal development and spiritual elevation in anticipation of receiving the Torah.
