Chapter 2:  Gifts needed by an abbot or abbess (paragraph 1)

Far from it, everything he or she commands or teaches should be like a leaven of the holiness that comes from God infused into the minds of their disciples. (From para. 1 of Ch. 2 of Saint Benedict's Rule, trans. by Patrick Barry, OSB, 1997.)

The leavening power of yeast lightens and expands dough; in the same way my relationship with the Teacher Within enlightens my mind.  But I believe it enlightens my mind through my heart.
