AS EXPOUNDED IN THE TORAH (GENESIS 2:21-23), God created the female form from the male's rib. The verse reads:
ויפל יהוה אלהים תרדמה על־האדם ויישן ויקח אחת מצלעתיו ויסגר בשר תחתנה: ויבן יהוה אלהים את־הצלע אשר־לקח מן־האדם לאשה ויבאה אל־האדם: ויאמר האדם זאת הפעם עצם מעצמי ובשר מבשרי לזאת יקרא אשה כי מאיש לקחה־זאת :
(21) And Hashem, God caused a deep sleep to fall upon the man, and he slept: and He took one of his sides, and closed the flesh in its place, (22) and of the side, which Hashem, God had taken from the man, He made a woman, and brought her to the man. (23) And the man said, This is now bone of my bones and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
One rationale behind God's choice to use the male's rib to create the female form follows the previously said reason that it is to instill a sense of deficiency or incompleteness in the male, propelling him to seek what is absent. This innate human impulse to search for what is missing is typically triggered when one recognizes a deficiency. As an example, this phenomenon is illustrated in the Torah portion, where the Torah (Genesis 2:5) asserts that no rain fell on the earth prior to man’s prayer; thus, one must recognize that something is absent in order to acquire it.
וכל שיח השדה טרם יהיה בארץ וכל־עשב השדה טרם יצמח כי לא המטיר יהוה אלהים על־הארץ ואדם אין לעבד את־האדמה:
And no plant of the field was yet in the earth, and no herb of the field had yet grown, for Hashem, God had not caused it to rain upon the earth, and there was not a man to till the ground.
Rashi (ibid) asserts that God intended for man to beseech Him for rainfall:
כי לא המטיר: ומ"ט לא המטיר? לפי שאדם אין לעבד את האדמה, ואין מכיר בטובתם של גשמים, וכשבא אדם וידע שהם צרך לעולם, התפלל עליהם וירדו וצמחו האילנות והדשאים:
BECAUSE GOD HAD NOT CAUSED IT TO RAIN — And why has God not caused it to rain? Because there was no man to till the ground, and there was, therefore, no one to recognize the utility of rain. When Adam came (was created), however, and he realized that it was necessary for the world, he prayed for it, and it fell so that trees and vegetation sprang forth.
If all our needs are effortlessly met, we will lose motivation to pursue further goals and desires, and our inclination to pray to God may decrease. It is essential to recognize that our achievements are not solely the result of our own efforts but are orchestrated by God's will, which governs the universe and our existence by taking into account everything from the grand scheme down to the most minor detail. This concept, known as Yahadus, underscores the significance of recognizing and submitting to the Divine authority of God.
