From Karl Rahner's Encounters With Silence

Only in love can I find You, my God. In love the gates of my soul spring open, allowing me to breath a new air of freedom and forget my own petty self. In love my whole being streams forth out of the rigid confines of narrowness and anxious self-assertion, which make me a prisoner of my own poverty and emptiness. In love all the powers of my soul flow out toward You, wanting never more to return, but to lose themselves completely in You, since by Your love You are the inmost center of my heart, closer to me than I am to myself.

Only knowledge gained through experience, the fruit of living and suffering, fills the heart with the wisdom of love, instead of crushing it with the disappointment of boredom and final oblivion. It is not the results of our own speculation, but the golden harvest of what we have lived through and suffered through, that has the power to enrich the heart and nourish the spirit. And all the knowledge we have acquired through study can do no more than give us some little help in meeting the problems of life with an alert and ready mind.
