Q: Why in the word shed (demon) included in God’s Name Shad-ai?
A: The yud in God's Name Shad-dai alludes to Godliness. If the yud is removed, all that is left are the letters shin and dalet, shed, which is the source of the English word "shadow." This refers to the situation in which God's reality is hidden, in the shadows, as it were. The rectification for this situation is to reveal the yud, the Godliness in every aspect of God's world. This rectification is particularly connected to the holiday of Sukkot, (Tabernacles) when we sit in the sukkah, in the shadow of faith in God.
