If we want to attain silence in the interior of our hearts, we ought to begin by investigating the causes of the clamor within us. Ordinarily there are two causes of interior noise: the imagination and the heart. How often it happens that we enter the presence of Jesus to converse sweetly with Him, and then the imagination begins to skip around, carrying us hither and thither… At other times, the source of the din is in the heart. Except in cases of abnormal agitation, the imagination never produces the clamor that the heart produces. When we are under the stress of some particular emotion, such as love, fear, desire, or anger, we cannot compose our spirit; our soul seems like a city full of noise.
–Luis M. Martinez (1881-1956)
