Those things that we "grasp", we understand. When we understand something, we can express it in words clearly enough that others may also understand. Kaph means the palm of the hand. In Cabala it has the special meaning of the hand grasping and the mental function of comprehension (grasp).

"Understanding, I express what I understand to others clearly."
"Through coming into harmony with the cycles of life, I am freed from the isolation of my former belief in the illusion of separateness."
