fear and fear of 'fear'

Palpitation of the heart generates a sort of sinking feeling, a fear, the fear of death. Here, fear is a physical phenomenon.
‘Fear can actually be recognized as something independent of the thing feared. Fear of death is only this fear in its pure form projected as fear of death, a sinking feeling in the pit of the stomach with any image or symbol of death.
All other fears are also similarly projections of the same fear, mixed with the symbols and images of the thing feared. Once I perceive this directly within myself I have no fear of ‘fear’, and therefore no fear of death
