There is also a second reason why the letters of thought, speech and action come from the Intellect of the Father, which is Chochma. Whatever is expressed and descends lower must have a higher source. For example, when a wall falls down, the stones at the top land the furthest from the base of the wall. So too in a person, the ability to express oneself outside of himself (with the letters of speech and thought etc.) come from a higher place in the soul than his ability to understand something. (The letters are actually separate from the knowledge and have a different source. As we see that the same idea can be expressed in many different ways with different letters. This shows that the idea is separate from the actual letters.) We see this in the fact that an animal and, le’havdil, a small child, are both able to understand what occurs around them, but are both unable to speak. The reason is that this higher part of the soul, known as Chochma, is not revealed in either of them. However, when the child’s mind develops, this part of his soul becomes revealed. So too in the G-dly soul, the letters of the Torah and the Mitzvos come from a higher place in the person than the understanding and knowledge itself, which is Bina. The letters come from Chochma, the Intellect of the Father.
