ייִדישער מחשבֿה אויף בראשית 7:22

G-d personally shaped the physical part, did not leave it to nature. That is why the Torah says "He fashioned," not as in other cases "Let the earth produce!" (Genesis 1,20 or 1,24). The word vayipach, He blew, refers to the original form, not to a self-supporting entity. Compare Genesis 7,22, "All who had the spirit of life in their nostrils, perished." Man then-- by his own efforts, not by having something blown into him by G-d-- completes the process of becoming a proper human being, converting potential achievements into actual accomplishments. The process is somewhat similar to the artist who makes a wax candle. He shapes the inert wax, inserts a wick (vegetable matter). Then along comes a man to light it and to illuminate the area around him, thus giving the candle its purpose.
