When a person's primary objective is to maximize material pleasures while minimizing discomforts, then life becomes a constant process of "pushing" (trying to push away from discomforts) and "grabbing" (trying to acquire or hold on to that which gives pleasure). With the loss of inner balance that accompanies a habitual "pushing and grabbing" approach to life, a deeper pain ensues-that of becoming aware of the ultimate unsatisfactoriness of the pleasure-seeking/pain-avoiding process itself.
