Near the conclusion of the bedtime prayer, wherein we say the Shema, is a Kabbalistic incantation to be recited three times: "In the name of HaShem, God of Israel: May Michael be at my right, Gabriel at my left, Uriel before me, and Raphael behind me; and above my head the Close Presence of the Holy One: the Shechinah.
Michael, who accompanies us, Uriel, the light of God who illumines a path forward, Gavriel, the power of God with his flaming sword, who clears out toxicity from our lives, and Raphael, the healing of God, who blesses us and heals from behind. And most importantly, the Holy Presence above us.
The understanding is that we are each surrounded by these angels. A helpful practice is to remember them, to acknowledge and talk with them, to articulate what you need from each of them, to thank them.
This painting was done in the style of the Book of Kells, except for the border, which is decidedly my own style. The whole makes an impressive image for meditation. One can imagine the sephirot within Uriel's candlelabra. The process in making this illumination is detailed in my blog.
