פירוש על קהלת 2:3

I searched in my heart. I repeatedly searched in my heart to grasp them all, partying, wisdom, and folly, and to stimulate and to pamper my body by imbibing in wine. Every luxurious banquet is referred to as wine [=יַיִּן.

“I searched in my heart to tempt my flesh with wine, and, my heart conducting itself with wisdom, to grasp folly, until I will see which is best for the sons of man that they should perform under the heaven during the limited days of their lives” (Ecclesiastes 2:3).
“I searched in my heart to tempt [my flesh] with wine” – Solomon said: “I searched in my heart to tempt [my flesh] with wine,” to tempt my flesh with the wine of Torah; “and my heart, conducting itself with wisdom,” with the wisdom of Torah. “To grasp folly” – Rabbi Yudan raised a question before Rabbi Aḥa: What is this that is written: “To grasp folly [sikhlut]”? He said: To grasp with wisdom [sukhlenuta].¹¹He interprets sikhlut to mean wisdom, as in the word sukhlenuta; this is the opposite of the common translation of sikhlut.

And my heart conducted itself with wisdom. Even if my body is imbibed with wine, my heart conducted itself with wisdom and Torah observance.
