Personal relationships require personal feeling. Here, the emphasis is on the small. The mystics can instruct us. We like to believe that the great mystics occupy themselves with the vaster cosmic things, but they usually talk about small things, very small things. With the feeling function they reduce intellectual speculations to matters close at hand, personal issues of food and nature. Their laughter is born from trivia. Our spoiled feelings are usually resentments over small things, those little mistakes that have been neglected as one goes along. Then life turns sour: one has soured one's life by missing the small feeling opportunities and one is left with festering minor irritations. To miss the small is to miss one's feeling function. Therefore, personal feeling needs to be expressed in small ways: personal favors, personal sharing, personal remarks about exactly what one likes in the other. The feeling function, by recognizing the other person's virtues, connects him to these parts, giving him belief in himself.
