420. Come and see the manna that came down for Yisrael in the wilderness. That manna was from the celestial dew that filtered down from the most concealed Atik, THAT IS, KETER. When it came down, its light was illuminating throughout the worlds and from it was sustained and fed the field of apple trees, THAT IS MALCHUT, and the higher angels. When the manna came down and the air of the world affected it, it gelled and its glow changed. It was not glowing any more, only as it says, "And the manna was like coriander seed ..." (Bemidbar 11:7). The atmosphere had even more of an effect on the angels THAT WERE THROWN DOWN BY THE HOLY ONE, BLESSED BE HE. As soon as they descended, they were transformed from that earlier level in which they were.
