It is "something like the color of electrum" (Ibid. 27), NOT EXACTLY ELECTRUM (HEB. CHASHMAL), THE SECRET OF 'CHAYOT ESH MEMALELOT' (LIT. 'MOTTERING FIERY LIVING CREATURES') BECAUSE IT CANNOT BE UTTERED, THE SECRET OF THE ILLUMINATION OF CHOCHMAH. But sometimes it is electrum, WHEN IT COMPRISES HADARNIEL, from which come all the Seraphim. FOR ELECTRUM (HEB. CHASHMAL) COMPRISES THE LETTERS "Cha-yot e-sh me-mal-et"; ALSO the living creatures exist and exist not, MEANING THAT THEY SOMETIMES TALK AND SOMETIMES ARE QUIET. Therefore it is electrum.
