(וחכ"א) אבריו של אדם מעידין בו שנאמר (ישעיהו מג, יב) ואתם עדי נאם ה' ואני אל:
The Sages say: A person’s limbs testify against him, as it is stated: “Therefore you are My witnesses, says the Lord, and I am God” (Isaiah 43:12), which indicates that each individual becomes his own witness and testifies against himself on the Day of Judgment.
(ג) ...אמר רבי לוי: ששה דברים משמשין את האדם, שלושה ברשותו ושלושה אינן ברשותו. העין והאוזן וחוטם, שלא ברשותו, חמי מה דלא בעי, שמע מה דלא בעי, מריח מה דלא בעי. הפה והיד והרגל ברשותו, אין בעי הוא לעי באורייתא, אין בעי לישנא בישא, אין בעי מחרף ומגדף היד, אין בעי הוא עביד מצוותא, אין בעי הוא גניב, ואי בעי הוא קטיל. הרגל, אי בעי הוא אזיל לבתי טרטסיאות ולבתי קרקסיאות, ואין בעי הוא אזיל לבתי כנסיות ובתי מדרשות....
(3) ...Rabbi Levi said: Six organs serve the human being: three are under his control and three are not. The latter are the eye, ear, and nose. He sees what he does not wish to see, hears what he does not wish to hear, and smells what he does not wish to smell. Under his control are the mouth, hand, and foot. If he so desires, he reads in the Torah, or uses bad language or blasphemes. As for the hand, if he so desires, it performs good deeds or steals or murders. As for the foot, if he so desires, it walks to theatres and circuses, or to places of worship and study....
Just as the Holy One, Blessed be He, sees but is not seen, so too does the soul see, but is not seen.
Just as the Holy One, Blessed be He, sustains the entire world, so too the soul sustains the entire body.
Just as the Holy One, Blessed be He, is pure, so too is the soul pure.
Just as the Holy One, Blessed be He, resides in a chamber within a chamber, in His inner sanctum, so too the soul resides in a chamber within a chamber, in the innermost recesses of the body.
Therefore, that which has these five characteristics, the soul, should come and praise He Who has these five characteristics.
