The subject of the prophetic vision is God’s deep plan. When He wanted to reveal it, He showed it in the form of the “Chariot”. The various parts of this Chariot have all been given their own individual names: these are the names of the Sefirot and the Partzufim, and the prophetic visions show all their different states and properties.
In an actual prophetic vision, the Sefirot and Partzufim may appear in many different forms and interrelationships, as we find in Kabbalistic writings about the various worlds and Partzufim etc.
