Fear is one of the six basic emotions.
“Fear and desire are the two things that rule us. Now, how much of a Master are we of those two things?” - Randolph Stone
“We understand why children are afraid of darkness, but why are men afraid of light?” - Plato
“Look about you in the world and you will see that the world of humanity is lost in its own ambivalence. It wishes to have this and wishes to go there. It wants to keep everything it has acquired and lose nothing, and yet it wants more than it needs. It is confused as to its predicament. It is confused as to the remedy. It is confused as to its identity. It is confused as to what to value and what not to value. All arguments and debates, all conflicts and all wars are engaged in exercising this ambivalence. (…) Look upon the world and recognize its utter confusion. This will teach you and remind you of the great need for Knowledge in the world.” - M.V. Summers
“Man today has become so material that he is afraid of any other experience than experiences of the senses. He thinks what he can experience through the senses is a real experience. And what is not experienced by the senses he thinks that it is something unbalanced, something to be afraid of, going into deep waters, something not normal, at least it is untrodden path. Very often man is afraid that one falls into a trance or a feeling which is abnormal. And those who experience them are fanatics, who have gone out of their minds. But it is not so.” - Inayat Khan
“(…) as you go away from Knowledge, you re-enter confusion and the world of imagination. As you come closer to Knowledge, you enter certainty, confirmation and a world of reality and purpose.” - M.V. Summers
