1. Man’s body was formed out of the earth but Woman’s body was formed out of Man’s body which was already a feeling, sensitive being. Our sages teach us that this is the source of a woman’s female character, temperament, voice and her developing both spiritually and mentally earlier than men.
2. At the creation of Woman, Man declares that after searching unsuccessfully all created beings, he could not find anyone who could stand beside him and join him in his mission as אדם until the creation of Woman. No other being on earth has free will. Woman stands alongside Man to become a complete אדם. The name אשה does not imply Woman’s dependance on Man but rather Woman’s equality with Man.
