All the Three Heads radiate in the Beard, for the latter is literally the revelation of this governmental order of Kindness-Judgment-Mercy.
All the Three Heads radiate in the Beard… It is stated explicitly in the writings of the ARI of blessed memory that all the Three Heads of Arich Anpin – the Skull, the Hidden Brain and the Cavity – are revealed through the Beard. And why is this necessary? …for the latter is literally the revelation of this governmental order of Kindness-Judgment-Mercy. The whole purpose of the Beard is to reveal the Kindness-Judgment-Mercy rooted in the Three Heads. This is why it is necessary for each of them to radiate in the Beard individually.
