The quote from Jodi Picoult's "Vanishing Acts" captures the profound transformation that occurs with motherhood. It highlights how, before becoming a mother, one may be unaware of the deep emotional void that a child fills in life. This realization often dawns upon new mothers as they experience the bond and love that comes with caring for their baby.

The sentiment emphasizes the inherent changes in priorities and feelings that accompany motherhood. It suggests that the journey of being a mother reveals a depth of fulfillment and purpose that was previously unrecognized, showcasing both the joys and challenges of nurturing a new life.
