Lamed | ל
Lamed is the sexual energy.
It represents the energy of teaching and learning. It is the only Hebrew letter that breaks the upper line, because in order to learn and teach (lilmod-lelamed), one must break the established structures and work beyond the limits imposed by the outside or by one's own inner self.
Through the energy represented by lamed, knowledge (daat) becomes part of oneself. As we have seen, the semi-sephira of daat represents knowledge, while the power of lamed represents knowledge that is not theoretical, but knowledge that is already within us. Through lamed, we have the energy to be able to look above the other letters, since true knowledge is the ability to look above all matters.
We should not be surprised that the Torah ends with a letter lamed, since it symbolizes that even though we have finished reading the text of the Torah, we must continue learning and teaching. The lamed thus shows us that we must begin again, because we always have something more to learn and teach.

Hod-Yesod
The energy of Hod-Yesod develops when my word reaches others. This energy is very difficult because the receiver, on the other side, is very varied. From my Hod I must make every possible effort for the best and most adequate communication. However, I am not responsible for all the subjective interpretations that exist in the Yesod dimension. My intention, from Hod, must be to communicate and to teach. The letter of the channel is the Lamed, which comes from lilmod, which is 'to teach' and 'to learn', so this energy is intended to teach and learn from the other. We must greatly refine our language to reach out in a merciful way to others. To teach is to transmit and to transmit is to teach the soul to find its own way. To teach is not to clone, it is to learn that my words help the other to find his own way and not to blindly follow my way.
Yesod-Hod
Society, the others, communicate to me their thoughts, their feelings, their joys and their sorrows. In the Hod of my soul I receive this energy as gratitude, which should always help me to grow. The question I must ask myself is: What can I learn from each one of those who interact with me? Because if I learn from the words of others, then I can always grow. If I close myself off from communicating with others, I unfortunately curb my own growth. My growth depends not only on the states of solitude of the "I" in the Tiferet, but also on how open I am to the thoughts of others. That openness to the thoughts of others leads to a steady growth of my soul into the higher universes.
