The Zohar, Chapter “Pekudei (Accounts),” Item 15: When the Creator said unto Moses, “Make the Tabernacle,” Moses was bewildered; he did not know what to do until the Creator vividly showed him, as it is written, “And see and make them after their pattern, which is being shown to you in the mountain.” “In their pattern” means that the Creator showed Moses everything in its higher, spiritual shape, and each of the spiritual shapes above was making its shape similar to the fictitious shape that was made below, on earth. This is how Moses knew.
This is what our work consists of because the spiritual world doesn’t have a form and we don’t know what Upper Light is by itself. This notion doesn’t exist at all separately from the creation. We can attain and define it only in relation to ourselves and through our sensations. However, our sensations are imaginary because we always feel reactions to an outside influence. We will never find out what actually is happening outside of us because we can’t extract ourselves from our perceiving senses.
It turns out that one can perceive properly only to the extent of the similarity of his properties to the spiritual properties. When the properties of man and the Creator coincide, man reveals the Creator to the extent of that similarity. Initially, we only perceive the imaginary form of this world. Our work consists of rising above it and asking for the Upper spiritual form to clothe in it. Once we have these two forms where one is confined within the other, we will acquire the proper perception of the world.
