Winter might conjure pleasant memories of playing in the snow, but it is hardly a season most of us would consider symbolic of childhood. We more naturally associate the 'winter of life" with a time when it is only our hair, if we even have any, that is snowy. Yet, the earliest stage of life is precisely what winter represents, according to the Maharal of Prague (Rabbi Yehuda Betzalel Loewe, 1525-1609) in his supercommentary to Rashi's on the Torah (Genesis 26:21). There the celebrated Jewish mystic and philosopher assigns a stage of human life to each of the year's seasons. A Western mind might associate nature's annual coming-to-life in spring with childhood, the warmth of summer with youth, autumn with pensive middle age and cold, slow moving winter with life's later years Â– think 'Old Man Winter." The Maharal, though, described things differently. He regards autumn, when leaves are shed and nature seems to slow down, as corresponding to older age; summer's warmth and comfort to represent our middle-years; spring to reflect the vibrancy and energy of youth. And winter to evoke childhood. Winter? Childhood? On the surface, to eyes unaided by deeper recognition, it might indeed seem strange; winter, after all, is a stark time, a season barren of activity and growth. But the superficial image betrays the reality. When spring finally arrives each year, after all, the new leaves haven't appeared ex nihilo. The buds from which they emerge have been developing for months, the sap in the seemingly dormant trees was rising even as the thermometer's mercury was falling. The evidence of life that at last presents itself with the approach of Pessah has been actively preparing its case since Hanukka. See for yourself. Go outside and inspect the leafless treesÂ‚ branches. The buds may be biding their time, but they are clearly there, ready to explode with green when commanded. WINTER, IN other words, evokes life's potential. And so, what better metaphor could there be for childhood, when the elements that will emerge one day as an adult are roiling inside a miniature prototype, when chaos may seem to be operative but when potential is at its most powerful? The Child, after all, as Wordsworth put it, is indeed 'father of the Man. ' In fact, we humans are actually compared to trees, in Deuteronomy (20:19). Even though the verse's context (the forbiddance to gratuitously fell trees during war), at least according to Rashi, implies a quizzical question mark at its end ('Is a man a tree of the field?"), other commentaries, like the Ibn Ezra, read the verse as making a straight comparison. And the mystical Jewish sources similarly see significance in the plain meaning of the words. AND SO the approaching winter holiday of Tu Bishvat (this year on January 22), the day the Talmud calls the 'Rosh Hashana for trees," should make us think about the potential that can lie in apparent chaos. It's a timely thought for other reasons too. A month after Tu Bishvat (two months, in a Jewish leap year like the current one) comes Purim, when we celebrate the turning of a seemingly hopeless and tragic situation into a joyous one. Esther was the bud, and when the right time came, she blossomed. And this time of Jewish year is when the weekly Torah reading concerns the Exodus, how, in the oppressive prison that was ancient Egypt, a redeemer came of age and, at the command of God, brought a people to bloom. So a conspiracy of factors pushes us to ponder the power of potential Â– in Jewish history (Esther and the Exodus); in the seasons of the year (those winter buds and sap); and in life (all the illustrious people who were once childish ones). The thought might reassure and animate us, even those of us of hoary head. For what emerges from the Maharal and Jewish history and the seasons is the lesson that what matters more than how many years may have managed to get behind us is the potential we still carry within us.
