Shabbat Tishrei 17 5704, Shabbat Chol Hamoed Sukot
Chumash: B'racha, Shevi'i with Rashi.
Tehillim: 83-87.
Tanya: XXIII. "The matter is (p. 523)...multitude) at all. (p. 525).
The soul-aspect of Yechida emerges through the Avoda of being tested. As is written (in the Hosha'anot service, p. 327):
"She clings and cleaves to you" - the binding of the soul to G-d. This leads to...
"She bears your yoke," observing Torah and mitzvot with self-sacrifice; and then...
"She, the One People (Yechida), affirms Your Oneness" - Yechida of the soul is revealed.
Through this revelation the Yechida of the animal soul is transformed into G-dliness. [1]
This finds expression in the intensity with which one fulfills Torah and mitzvot, with an inner enthusiasm, with a sense of great delight and tremendous pleasure in serving G-d.
(To a person on that lofty level) there is total equanimity to all worldy matters; "yes" and "no" have become absolutely equal to him, for he is now divested of the sense of delight in and appetite for material things.
Notes:
The animal soul is not comitted to evil, or even to self-indulgence. Its primary desire is pleasure; but its concept of pleasure can be modified, so that it need not seek physical delights.
