"¡Hay que vivir! Y él me enseñó a vivir, él nos enseñó a vivir, a sentir la vida, a sentir el sentido de la vida, a sumergirnos en el alma de la montaña, en el alma del lago, en el alma del pueblo de la aldea, a perdernos en ellas para quedar en ellas."

"It is sad not to love, but it is much sadder not to be able to love."

"Life is doubt, and faith without doubt is nothing but death."

"My religion is searching for the truth in life and life in the truth, though knowing that I do not have to find it while I live; my religion is fighting incessantly and tirelessly with the unknown."

"Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea."
