We learn how speech arises through the body, and the effect of speaking the Sh'ma Yisrael and the Amidah. The Faithful Shepherd talks about the speech and silence of the beasts of fire in Ezekiel's vision.
We are told that the two lobes of the lungs (the two halves) parallel the two lips of the mouth and, together, they help create the miracle of human speech, which ascends upwards. Speech holds tremendous spiritual power. As such, negative speech creates destructive forces that bring chaos and illness to our lives. Here, through the wisdom of the Zohar, we cleanse our mouths and lungs from any illness caused by negative speech such as slander, curses, gossip, and evil speech about another person. All the destructive words spoken throughout history are hereby corrected and cleansed.
The spiritual forces that ignite during the utterance of the healing prayer Sh'ma Yisrael nourish, purify, and heal the 248 parts of the body and soul - personally and in the collective body of man.
The holy words of the righteous souls throughout history, recited during the Sh'ma and the Amidah prayers, are now summoned forth, kindling a great Light in our lives as they join the Upper and Lower Worlds.
