619. When they are all comprised in Zechut El, he issues a living creature. This is a glowing living creature, called 'Tumiel'. It stands guard over the world by the eyes of Hashem, who hover and walk about the world. These eyes of Hashem are watchful over the good deeds done secretly, and watch over the deeds done with a whole heart, though not done properly.
623. When the four Seraphim travel, sparks of fire come out. From the sparks 72 wheels glowing with fire were made, whence the river of fire was made. Thousands will serve this river. All the four Seraphim watch over those who give pleasure to the Shabbat. The living creature Tumiel is above them, and they travel according to it and under it.
