When you love, you are not lonely. The sense of loneliness arises only when you are frightened of being alone and of not knowing what to do. When you are controlled by ideas, isolated by beliefs, then fear is inevitable; and when you are afraid, you are completely blind.
I am asking myself what is fear: not what I am afraid of. I lead a certain kind of life; I think in a certain pattern; I have certain beliefs and dogmas and I don't want those patterns of existence to be disturbed because I have my roots in them. I don't want them to be disturbed because the disturbance produces a state of unknowing and I dislike that. If I am torn away from everything I know and believe, I want to be reasonably certain of the state of things to which I am going. So the brain cells have created a pattern and those brain cells refuse to create another pattern which may be uncertain. The movement from certainty to uncertainty is what I call fear.
