“Deep in his burrow he’s safe from other mouths. It’s his own hunger he has to escape. Winter has wiped bare his vegetarian table. He would starve if he stayed awake. Asleep—a sleep so deep his heart barely beats and his body cools to nearly the temperature of ice—he expends almost no energy. Only at a glacial pace does he burn the fat he added eating up to three pounds of greens and fruit each lush day of summer. In deep sleep his hunger is subdued, his substance shrinks, but is not consumed.”
–Gayle Boss, All Creation Waits: the Advent Mystery of New Beginnings, p. 45
