The experience of frustration comes from the separation we impose between our yearning and our fear. Generally, we yearn for that which we fear, or at least fear the unknown (mystery, and therefore and paradoxically, truth) that will be caused through the pursuit of yearning. The more the separation between these two, yearning and fear, the more frustration if you are conscious, or the more neurosis if you are not (literally, “I can’t stand the frustration, I’m going crazy”).
