Fear

*******

Human nature is part "lower" and part "higher" nature. The lower is dominated by fear, and is much more powerful and developed than the higher in most people.

Fear and Love are opposites. (Hatred is only a form of fear.) Throughout their karmic history, people have feared more than they have loved. So, fear has proliferated and multiplied, while most souls just do not have the same quantity of Love in their histories.

Since the start of human history, many fears, built into biology, served survival, and so, were helpful. But most fear is harmful or damaging, and of no spiritual value. It is one goal of the mystic (although it might take lifetimes) completely to replace all fear with Love: What she now fears she wants to learn to Love. Love neutralizes and vaporizes fear, while fear blocks the free Flow of Love.
