For the Dew of Bedolach is seen to contain all the colors together. As explained in the Zohar, it clearly contains both Kindness and Judgment: “It is white, but a red color is visible in the white...” (Idra Rabba 128b and see 132b). Thus all the colors are visible in the bedolach stone: no one color rules out another. However here in the Unknown Head, one thing rules out another.
However this Head appears to be one thing and then immediately afterwards it seems to be not this but the very opposite of what we saw. It seems as if we were mistaken in how we saw it at first, and that it is different from the way we saw it. It remains in this state of constant transmutation... This is clear as discussed in the previous Opening in connection with the impossibility of determining the source of the mode of government.
