This entire composite weave is visible to the prophets or the souls, and this is what is called the Chariot (מרכבה, Merkavah). The actual powers of the Supreme Thought are invisible, for they are simple and cannot be seen in their intrinsic essence. Yet the Supreme Will wanted them to be visible through lights and prophetic likenesses and images, and to appear in all the different aspects that we ascribe to them: Partzufim, worlds, one clothed in another, ascending, descending, and so on. However, we already know that this is not how these powers are in reality: this is only how they appear in the prophetic imagination.
The Merkabah as a Tapestry of Divine Revelation
