This state of love is born anew in the heart through experiencing Light in meditation. Newborn love expresses the element of fire in the soul, while the natural and calm flow of instinctive love expresses the spiritual element of water. The effect of the Jew's loving performance of Torah and mitzvot on G-d is compared to the effect of food on the body.
Food provides energy that binds the soul to the body in an integral unity.
Without sustenance, there is spiritual and material disharmony leading to eventual separation of soul from the body. Two forms of light radiate from G-d into the Creation. The second is the light that is uniformly present in all worlds. This light is hidden because it is too great for finite vessels to contain. It therefore remains transcendent.
