Shalom Aleichem: Shabbat Gifts
We receive a Nesham Yeteira, an additional soul, on Shabbat, representing enhanced abilities and opportunities to perceive holiness. Its purpose is to enable the person to draw out and realize his or her own potential for spiritual growth.
The Shela HaKodesh comments that every such God-given gift is within the realm of the angels, for it is a Divine creation meant for a particular purpose like the angels themselves.
These are the “Angels” whom we greet as the Shabbat begins. (Torat Chesed)
