Question: When does faith turn into attainment?
Answer: If it is faith above reason, then it becomes a vessel (Kli) for attainment. After all, the light of Hassadim is called faith.
Faith above reason is a quality of bestowal that reigns over the will to receive. The will to receive with the intention to bestow becomes a vessel (Kli) for the light of Hochma.
Then the light of Hochma, clothed in the light of Hassadim, reigns inside the will to receive, and this is attainment.
Filling the light of Hassadim with the light of Hochma is called full or complete faith (Emuna Shlema).
