How the Sefirot appear in the prophetic vision. The images seen by the prophets and what they represent.
The Sefirot can shine with an abundant radiation of light or with diminished radiation. They can appear in numerous different forms and likenesses, although in truth they possess no form or appearance. It is just that they appear in some form or likeness, but one who examines them will see that in truth, the form and likeness are purely contingent upon the observer, as stated in the verse, “And in the hand of the prophets I have used likenesses” (Hosea 12:11). In their essence, however, the Sefirot are only an extended array of powers organized in their necessary order, interdependent in their various laws and influenced by one another, as required according to the perfection of the entire ordered plan.
