What is the role of the soul?
But without the soul we wouldn’t exist!
The soul is that which comes from the Divine without ever leaving Him, and returns to the Divine without ceasing to be manifest.
The soul is the Divine made individual without ceasing to be divine.
In the soul the individual and the Divine are eternally one; therefore, to find one’s soul is to find God; to identify with one’s soul is to unite with the Divine.
Thus it may be said that the role of the soul is to make a true being of man.
